Our guest this week is Jennifer Conroyd of Fluid Running is joining us to confirm that "aqua jogging" as we called it in the Tim O'Donnell interview is in fact the next big thing. Jennifer is an Ironman finisher and also a 15 time Boston Marathon qualifier. She is an expert on fluid running and is here to tell us all about how to do it right, the science behind it, and why more and more professional athletes are turning to it.
Thanks to last weekend's guest, Leadville 100 Trail Run finisher Jason Cohen and his journey to transform himself from a body weight of nearly 300lbs to the fighting weight of an ultramarathoner. You can listen to the interview on episode #215.
Jason mentioned his weight loss competition that he has with his peers who were also obese at the time. I did that a couple of times early in my career with co-workers. First was my 30's and we called it "battle of the fatties". The second time was in my early 40's, different job when I was traveling to Virginia every week. Again, we called the competition "battle of the fatties" and we did it as a percent of weight loss over two months. I mentioned during the interview with Jason that was 179, which is about 10 pounds heavier than I want to be at this time of the year. One of my athletes that I coach, Matt, is about the same weight and we both want to lose 10 pounds. Our goal is to get to 170 by St. Patrick's Day on March 17th.

Interview with Jennifer Conroyd:
Jennifer Conroyd is the founder of Fluid Running, a deep water exercise program. She is an avid athlete, Boston Marathoner and Ironman. Jennifer discovered the benefits of deep water running when she sustained an injury while training for the Chicago Marathon.
Due to her injury, she could no longer train by running on the road, so she took to the pool and ran solely in deep water for the six weeks leading up to the marathon. She not only finished the marathon but qualified for the Boston Marathon.
Amazed by her successful finish, she created Fluid Running in 2011 with the goal of helping other injured runners. Fluid Running was voted as one of the Top 20 Best Workouts in America by Men’s Journal.
Let's get into the interview now with Jennifer Conroyd.

Fluid Running Discussion:
I just heard another interview on another podcast I listen to with pro triathlete, Lisa Roberts, who talked about how she used deep water pool running to train during running injuries.
I've now done three sessions, one using the app and a Jennifer Conroyd led training session. The other two were at the end of my swims, where I spent 10-15 minutes with the Fluid Running belt only and just run. I keep forgetting to bring my heart rate monitor, but I'm eager to see how high I can get it in water.
I know so many people who are sidelined from running right now due to running injuries and talked with them about pool running as an option. The first reaction I get is, "you mean that thing that the old people do with the floaty belt?" There's a stigma that is the discussion here. We are evolutionarily hard wired to not show weakness. If that's what the old and feeble are doing, I can't be associated with that. Older athletes (yes, they are athletes…just older), have been in their bodies longer and know what's good for it. And yes, many of them can't take the pounding of running so they are staying fit.
I've listed about a half dozen great links to more information from Fluid Running here in the show notes. There will also be a section in the Resources page before the end of the weekend.

Some additional studies:
I looked into Effects of Hydrostatic Weight on Heart Rate During Water Immersion and found an article by that name. Here's an excerpt:
"central blood volume is increased through the redistribution of venous blood and extracellular fluid from the lower to the upper part of the body in the same way as during face immersion reflex (Campbell, Gooden, & Horowitz, 1969). As a result of the increase in plasmatic volume in the central part of the body, the heart and central circulation are distended, leading to stimulation of volume and pressure receptors of these tissues, which in turn leads to a re-adaptation of the cardiovascular system,

increasing central venous pressure, cardiac output, and stroke volume, and finally lowering HR (Watenpaugh, Pump, Bie, & Norsk, 2000).
Last week we discussed the TrainingPeaks University course, 'The Science of Endurance Hydration'. I'm still taking it and want to complete it before I give my report. I will tell you that part of the reason it's taking a while, is that there is a lot of additional reading they make available.

What's New in the 303?
Boulder, CO – iKOR Labs, the Boulder-based producer of recovery-enhancing hemp oil/CBD (cannabidiol) products, today proudly announced the addition of Andrew Pruitt,EdD as Sports Medicine Consultant for Science and Innovation.
Pruitt, a legend in the endurance industry, has been putting his golden touch to use for decades. He received a Bachelor of Science in Anatomy from Iowa State University and moved to Colorado in 1973 to join the sports medicine staff for Colorado University Athletics, eventually becoming the Director of Sports Medicine.
Denver is switching its bicycle program into high gear to help keep its promise of installing 125 miles of bike lanes by 2023.
Mayor Michael Hancock on Thursday announced the new three-pronged approach, alongside Denver Transportation and Infrastructure Director Eulois Cleckley.
The accelerated plan will coordinate striping bike lanes when streets are paved; install “high comfort” lanes that include physical barriers to separate cyclists from cars; and “significantly” expand the bike network in the city’s most densely populated areas, like northwest and central Denver, to increase the number of households within a quarter-mile of a high comfort bikeway.
Hancock on Thursday said that the “reality is we’re ushering in the bicycle revolution in Denver, Colorado,” Denverite reported. “I grew up in the city. We didn’t have bike lanes. We rode our little Huffys without bike lanes, protected or striped. And today we get a chance to see a city committing to creating comfort lanes for people to ride their bikes.”
