Podcast appearances and mentions of Crissy Field

It is Fleet Week in San Francisco. Are you coming to the city to see the Blue Angels and the ships? What is Fleet Week? San Francisco Fleet Week is one of the country's largest celebrations of the U.S. armed forces. The celebration was started in 1981 by then San Francisco Mayor, Diane Feinstein. Organizers say following the pandemic huge crowds turned out for Fleet Week last year, and they're predicting big crowds again this year.  Where is it? Most official Fleet Week activities take place along The Embarcadero and Marina Greens. If you're looking for the best seating for the airshow, the Marina Green is the place to be. The Presidio Tunnel Tops, Twin Peaks, Pier 39 and Crissy Field will also provide great views. Watching the Air Show is free, but premium seating is available for purchase.  City leaders are advising visitors, as they have in years past, to use public transit and say if you must drive, be sure to not leave any valuables in your vehicle, in fact they're warning people who drive to clear any valuables out of their car even before they park, just in case burglars are watching. What's new in 2022? Organizers say for the first time ever Navy F-35's will be at San Francisco's Fleet Week. Two of the F-35's will be on display for visitors to enjoy.  Say something good about yourself - it's ‘Toot your Flute” DaySee omnystudio.com/listener for privacy information.

To improve our endurance, we want to be more efficient at an aerobic intensity. To improve our speed, we want to have a higher anaerobic capacity. Besides doing "field testing" like the Swim CSS, Bike FTP and Run TT, one scientific way to test is how well the body processes muscle lactate. If you've ever done a Lactate Threshold Test (LTT), here's how the test administrator interprets the lactate measurement to determine your training zones.   The LTT is performed by starting the athlete a warmup at a very easy intensity. We'll use the run discipline for this example. The athlete will walk on a treadmill for 10 minutes before starting the test and once the test starts, the intensity is increased every 2 minutes. At the beginning of the 10 minutes, the test administrator takes 4 metrics - pace, rate of perceived exertion (RPE), heart rate (HR) and lactate millimoles per liter of blood with a blood sample and lab kit. The lactate compared to the pace is the primary metric and the HR and RPE are secondary but useful to confirm and interpret the data. The administrator takes those same 4 metrics at the end of the 10 minutes and every 2 minutes there after. Every 2 minutes the treadmill pace is increased by 30 seconds of pace (11:00, 10:30, 10:00, 9:30 and so on).   There are two key inflection points the test administrator is looking for. When the intensity is increased and the lactate level remains the same as the previous level means that the subject athlete is predominantly aerobic (zones 1-2). When the lactate level increases and levels out after each increase the athlete is in between aerobic and anaerobic (zone 3). When the lactate level continues to rise without an increase to intensity, the athlete is above lactate threshold (zone 4-5).   Our News is sponsored by Buddy Insurance.

Garmin has released the Varia RCT715, a new version of its tail light that features a high-definition camera to record any incidents out on the road.   The Varia RCT715 features the same radar technology as its predecessors. When paired with a Garmin bike computer or smartwatch, the Varia will alert users to vehicles approaching from behind up to 140m away. Garmin says the device can be paired with selected cycling apps such as Ride with GPS. This will enable users to overlay maps with the radar notifications.   Garmin claims the Varia RCT715's tail light can be seen up to one mile away in daylight. The camera records continuously and will save footage if an incident is detected. Garmin says the Varia's camera will “capture sharp, clear footage” at up 1080 pixels and 30 frames per second.   The camera will record constantly when the Varia is in use. If an incident is detected, via Garmin's Incident Detection feature, the camera will automatically save footage from before, during and after the event. According to Dan Bartel, Garmin's vice president of global consumer sales, this is to provide users with evidence of an incident “should they ever need it”.   However, the camera also provides more recreational functions, in line with how you might use a GoPro. Via the Garmin Varia app, users can access the video footage, transfer files and customise the camera's settings, to do things such as overlay data, including speed and location.   Garmin says the use of the camera will be prohibited or regulated in some jurisdictions, adding that it is the responsibility of the user to know and comply with applicable laws and rights to privacy. While Garmin has added a camera to the Varia, it has retained the radar and tail light functionality of the device.   Like the previous Garmin Varia RTL515, the radar on the new version will still detect and alert users to vehicles approaching from behind to the same distance of 140m.   Similarly, the tail light on the new version is said to be visible up to one mile away in daylight, which is the same as the Varia RTL515. But while the RTL515 has a claimed battery life of up to 16 hours, the RCT715 has a shorter claimed battery life.   The Varia RCT715's battery life is said to be up to four hours with radar and the tail light on ‘solid high' or ‘night flash', and up to six hours with the light flashing. The reduction in battery life is presumably because the camera is recording continuously.   Why Running at Night Feels Harder An interesting new study by researchers at Sweden's KTH Royal Institute of Technology, working with the Swedish military and colleagues in Slovenia. They'd noticed that soldiers on night marches seemed to burn more energy than would be expected from the physical demands of the mission, especially when wearing night-vision goggles that restrict peripheral vision. They wondered whether not being able to see forced the soldiers to alter their strides, sacrificing efficiency for stability, so they decided to test this theory.   The new study, published in the European Journal of Applied Physiology, had 15 volunteers do a series of ten-minute treadmill walks in four conditions: with and without a 56-pound pack, and with and without a blindfold on. The treadmill was set at a comfortable pace of around 30 minutes per mile, with a laser warning system to alert them if they were about to fall off the back of the treadmill.   The results showed that oxygen use (a proxy for energy consumption), breathing, and heart rate all increased substantially when wearing the heavy pack, as you'd expect. The surprise was that they increased by nearly the same amount when adding a blindfold. Here are the graphs of those three parameters, with (circles) or without (squares) the blindfold:   If you compare the circles on the left (i.e. blindfolded with no backpack) to the squares on the right (i.e. not blindfolded with a backpack), you see they're almost the same. In other words, walking with a blindfold takes as much extra effort as walking with a 56-pound pack. To be precise, the backpack increased oxygen consumption by 20 percent, while blindfolding increased oxygen consumption 19 percent.   The explanation for this effect seems to be that the subjects adjusted their strides when blindfolded: their steps got 11 percent shorter and 6 percent wider, and they also lifted their feet 18 percent higher. Bear in mind that this is on a perfectly flat treadmill, so there are no bumps or potholes to avoid: this is just an instinctive response. It's also worth noting that the effect probably isn't just because they're unfamiliar with the challenge of walking while blindfolded: a similar test of blind subjects found that they burned about 25 percent more energy while walking than sighted controls.   Of course, being blindfolded is significantly more disruptive than wearing night goggles, or simply being out at night in poorly lit conditions. That means the size of the effect is probably exaggerated. And walking is different from running. But it seems reasonable to assume that similar mechanisms are at work when you're running in the dark—along with other, more subtle mechanisms like optic flow, which is the pattern of objects flowing through your vision as you move through space.   When you're running or cycling in the dark, you can only see objects that are relatively close to you. That means that they appear in your field of vision only briefly before disappearing behind you, which corresponds to faster optic flow than you'd experience in daylight. A few previous studies, most notably those by Dave Parry and Dominic Micklewright of the University of Essex, have tried manipulating optic flow in virtual reality setups, making the scenery fly past more quickly or slowly than the speed of the treadmill or exercise bike. Sure enough, when optic flow is faster—as you'd experience in dark conditions—you feel like you're moving faster, and any given pace feels harder.   There's an interesting corollary to these findings about optic flow, as Parry explained to Runner's World's Scott Douglas back in 2012. “Running in an environment where most of the visual reference points you can see are close by, you experience a greater sensation of speed than when in an environment where your reference points are far away,” he said. That means running through a forest or through city streets will likely feel faster than running across an open field.   Ever since reading about those optical flow results, I've dismissed the gap between my actual and perceived pace during night runs as a quirk of how my brain estimates effort. During most of my runs, that gap doesn't matter—but if I'm trying to do a tempo run or hard workout before sunrise, the slower pace can be a bummer. So I'll take the new Swedish results as reassurance that night running might really be physiologically harder, not just a brain error—and if that's what it takes to avoid tripping in the dark, I'll accept the trade-off.   What's New in the 303:   Ragnar Snowmass RUN.

That means running through a forest or through city streets will likely feel faster than running across an open field.   Ever since reading about those optical flow results, I've dismissed the gap between my actual and perceived pace during night runs as a quirk of how my brain estimates effort. During most of my runs, that gap doesn't matter—but if I'm trying to do a tempo run or hard workout before sunrise, the slower pace can be a bummer. So I'll take the new Swedish results as reassurance that night running might really be physiologically harder, not just a brain error—and if that's what it takes to avoid tripping in the dark, I'll accept the trade-off.   What's New in the 303:   Ragnar Snowmass RUN. CAMP. SLEEP? REPEAT.   Ragnar Trail Snowmass-CO presented by Salomon brings you the perfect fusion of trail running, high-country camping, and Rocky Mountain beauty. Teams of 8 (or 4) will find their inner wild on three separate mountain trails, or “loops" that start and finish at Ragnar Village. Glacial valleys, snowcapped peaks, and blooming wildflowers set the scene as you make your way along rolling single-track. Though you may blame the altitude, in the end it will be the stunning mountain views that take your breath away. Conquer each climb and you'll be rewarded with panoramic views of the Maroon Bells -Snowmass Wilderness — not to mention a much needed downhill.   Without Limits Productions May 13 at 8:30 AM  · This season we usher in a new era of cyclocross, but an era built upon the champions and friends who have defined excellence over its past 23 seasons.  We're proud to announce, on the 1-year anniversary of her tragic passing, the new Gwen Erffmeyer Inglis Cup for the SHIMANO Cyclocross Series - Women OPEN Series Champion!   Upcoming Multisport Events in Colorado (runningintheusa.com) Upcoming Classic Races in Colorado (runningintheusa.com)   Video of the Week: Ragnar Trail Snowmass - CO       Upcoming Guests: World Champion Adventure Racer, Robin Benicasa with us today.

Welcome to Spiritually Fit Yoga! Enjoy this episode! Biography for Greg McCormack Greg grew up exploring the rural woodlands in the Farmington River area of Connecticut, and the shorelines of LaJolla, California. His passion for the marine environment flourished when he got scuba certification in his teen years and went on to work summers at the Catalina Island Marine Institute. Greg received his Bachelor of Science degree from Humboldt State University after transferring from UC San Diego. Driven by a desire to connect people with the outdoors, he has worked as park ranger in many of the nations most iconic parks, including Grand Canyon, Everglades, Hawai'i Volcanoes, Denali, Mount Rainier, Olympic and others. Southeast Alaska's vast wilderness inevitably stole his heart when he first arrived in 1994 as a guide aboard a 36-passenger expedition vessel. He spent many summers there leading clients on sea kayak and river rafting trips. He branched out as an expedition leader, lecturer and Zodiac driver on dozens of trips to the Arctic, Antarctic, Sea of Cortez, and Caribbean. As a Divemaster, he has led divers in the turquoise South Pacific waters of Polynesia, Melanesia, Micronesia and Indonesia. Greg did a couple of stints for the National Oceanic and Atmospheric Administration, working as a marine educator in the Olympic Coast National Marine Sanctuary and recently the Greater Farallones NMS in San Francisco at Crissy Field in the Presidio. Greg has done volunteer work all of his life, including the last 8 years as a guide at the Monterey Bay Aquarium. He did a 6-week long stint two years ago as an albatross census counter for the U.S. Fish and Wildlife Service at Midway Atoll in Papahanaumokuakea Marine National Monument in the northwestern Hawaiian Islands. Outside of work, Greg can be found trail running in the park districts near his home in Monterey, California. He enjoys active vacations with his touring bicycle, logging many thousands of miles in many of the 91 countries he has visited. His mission statement is to have first-had experience as an educator in as many of the worlds remaining intact ecosystems before more environmental degradation occurs and inspire others to become stewards of this magical blue planet we call home. ================================== Contact Greg on Instagram @greg.mccormack and at http://www.gregmccormack.com ================================== Thank you for being here!

"They gave us little solar lamps, since it was getting dark. We could see the sun setting on the sea. The day was something very special, very magical." - Matilde Tellez, Good Samaritan Hear our rangers Mariajose and Fatima with special guest Matilde Tellez's audio postcard remembering their magical Crissy Field moments.

Hey Area is where we find answers to questions you ask. Brit Byrd wanted to know, “Why does San Francisco have the Farallon Islands? They’re thirty miles off the coast, but they’re legally part of San Francisco. What’s up with that?” The Farallones are these islands off the coast of San Francisco, and Brit noticed them on the internet. One day he was looking at San Francisco and noticed that the county line jutted thirty miles out into the ocean and circled some tiny little dots. On a clear day you can just make out the islands from the city — they’re like jagged teeth sticking out of the Pacific. To understand why they’re part of San Francisco you first have to understand what they’re like, so I went to the visitor center for the Greater Farallones National Marine Sanctuary. It’s at Crissy Field in the Presidio. These days the islands are protected as a national wildlife refuge, and only a handful of people get to set foot on them. One of those lucky people is Mary Jane Schramm . She

Nathan Amy brought a gym to the beach. In fact, he can bring a gym anywhere in San Francisco. With his new fitness company Kokoda, Nathan uses a mobile fitness truck to bring a gym to you. The truck is loaded up with tons of fitness equipment. Nathan can pull in to any location, unload his equipment, and set up a fully functional gym in a matter of minutes. Most of the time, his gym is set up at East Beach right next to Crissy Field. He leads classes there six days per week. I recently joined Nathan at East Beach for his Functional Fitness class. Let me tell you, it did not feel like I was at the gym. On a crystal clear evening, I worked out as the sun set over the Golden Gate Bridge and a light breeze blew in from the bay. The view was incredible and the workout was intense. I was still feeling it a few days later! Nathan's journey to starting up Kokoda is an interesting one. He grew up in the Australian Outback and joined the army at the age of 17. After leaving the army, he worked various jobs in the private security sector in Kabul, Afghanistan. At a United Nations barbecue, he met the love of his life and that led him to San Francisco. Nathan lives in the Marina and shares his favorite spots there and throughout San Francisco.

On any given day and in all types of weather conditions, nature artist Bill Dan can be seen balancing rocks at Fisherman's Wharf, Crissy Field or on the waterfront of Sausalito. Since he began this practice in 1994, he has become a well-known local figure, often attracting large groups of spectators who gather around him while he creates vertical rock sculptures that seem to defy gravity. Completely self-taught as a rock balancer, Bill Dan plays upon the possibilities inherent to the interaction of rock, mass and gravity to create his nature art.

Ocean tides rise and fall twice a day, influenced by the gravitational forces of the sun and moon. Studying tides' rhythmic movements helps us understand both the ocean and the cosmos. Astronomer Ben Burress explains how tides work, and QUEST visits Crissy Field in San Francisco to see the oldest continually operating tidal gauge in the Western Hemisphere.

A weekly handful of weird, wonderful and wacky happenings dredged up from the kaleidoscopic depths of San Francisco history. October 1, 1938 On a foggy Saturday in 1938, a swaybacked, 12-year-old horse named Blackie swam -- dog-paddled, really -- completely across the choppy waters of the Golden Gate. The horse not only made aquatic history with that trip, but he soundly defeated two human challengers from the Olympic Club, and won a $1000 bet for his trainer Shorty Roberts too. It took the horse only 23 minutes, 15 seconds to make the nearly mile-long trip, and the short film made of the adventure shows that Blackie wasn't even breathing hard as he emerged from the waters at Crissy Field. His trainer Shorty couldn't swim, but he made the trip, too -- and this was part of the bet -- by hanging onto Blackie's tail. A rowboat led the way, with Shorty's brother offering a handful of sugar cubes from the stern to keep the sweets-lovin' horse on track. read on ...
