Muscle Damage and Running Economy (Part 2)

Image
"It's the economy, stupid."      The implications of muscle damage during endurance events presents a paradox - the very act of racing progressively reduces our ability to maintain race pace. But it's not as simple as just muscle damage leads to reduced running economy. While the data we collected in our research project described in Part 1 demonstrate acute effects of muscle damage, the real-world implications during long races like marathons and ultramarathons are more complex and potentially performance limiting.      During a marathon, muscle damage accumulates through the race. Unlike the controlled laboratory setting where damage is induced through a single session of eccentric exercise, race-day muscle damage is compounded by multiple factors: repeated eccentric loading from thousands of footstrikes, environmental conditions, terrain, and the high-intensity nature of racing. By mile 20, when many runners hit the proverbial "wall," they're not jus...

Muscle Damage & Running Economy (Part 1)

     For a class project in grad school, we had to come up with a research topic and collect pilot data in the lab... Being the endurance nerd I am, I somehow convinced my lab partner (who had little or no interest in running) that we should look into the effect of muscle damage on running economy.      We decided we'd collect running economy data using a metabolic cart while running on the treadmill, complete a "muscle damage" protocol then collect running economy data again 48-hours post muscle damage. I hypothesized we'd see a decrease in economy (and it'd feel absolutely awful).      I don't think I've ever been or ever will be more sore than I was after completing 6 sets of 10 eccentric leg press AND 100 depth jumps from 60cm. I stumbled out of the weightroom on Jell-O legs and my running would suffer for nearly a week - just from one workout that took less than an hour to complete.      A couple days later, we saw an inc...

Death March Revival ITT Ride Report

Image
 I don't know what got into me Last year my wife, Courtney, rode all three of Tennessee Gravel's  individual time trial (ITT) routes. And she really enjoyed it. But I had very little interest in trying to ride these long, hard routes as fast as possible - all by myself. I saw Chad Hungerford set the fastest known time (FKT) on the Death March Revival (DMR) route last May at 7 hours 41 minutes and I thought, "that looks miserable." I had a hard time imagining putting forth a constant effort, suffering for 7+ hours over these rough roads and long climbs. That said, I did ride the DMR route last May - but I rode it with Courtney and a few friends. It was a long day out at a casual pace, completing the loop in about 11 hours. And that was really enjoyable. It wasn't super exciting - I might rather spend my time ripping down some singletrack, but it was a beautiful day through my favorite mountains. I had also ridden most of the route (excluding the Big Frog loop) with...

Fools and Fanatics

Image
I'm not a philosopher, but I know as a coach, trainer, or athlete - it helps to have some core beliefs. Without those, how do you justify your approach? How do you formulate workouts, season plans or adapt to changing circumstances? How do you make any decisions? You have to believe a certain approach can lead you to a certain result. And hopefully those beliefs are rooted in something - education, personal experiences, literature, observations, etc. I like to think there is something of a "Spectrum of Belief" or spectrum of coaching styles.   On one end, a coach or athlete believes there is one absolute best way to train for an event. On the other, the individual believes nothing matters - decisions in training or training itself makes no difference. I think good coaches reside in the middle of this theoretical spectrum. They are able to make decisions based on their knowledge and experiences  - believing those decisions will lead them and their athletes in the right d...

That's a Wrap!

Georgia Gravel Grinduro Shortly after my last post, Long Course Duathlon Nationals was cancelled. And for a few days, I thought my racing season was over, before it really began - but then a friend mentioned the Georgia Gravel Grinduro in Helen, GA on Halloween. Perfect! - I could use the event as a carrot to train for and as a final race before getting reset for 2021. Training was a balance of short hard intervals, and long rides; then a few fun mountain bike rides and gravel adventures with my wife. I was also running a bit more (25-35 miles per week). I put very little pressure on myself and tried to take a low key approach to the race. It was just supposed to be fun, and a good way to challenge myself. Despite the "low-key and fun" approach to training, I was able to put up some of my best ever numbers for 3-minute intervals and set PR's on some long Strava segments. So, I was happy to have good legs heading into the race. I figured Elliott Baring would show up (he be...

Fall Updates

2020 Powerman Zofingen The Powerman Zofingen ITU Long Distance Duathlon World Championship has been postponed until May 2021. At this point, I'm not certain that I will make travel grants available again in 2021. Check back in January for an update. Trans-North Georgia Adventure Since most races were cancelled this year - and I didn't have to dedicate myself to duathlon, running, road cycling, or anything specific - I decided to have fun, try something totally different and sign up for the Trans-North Georgia Adventure (TNGA) race. I grew up riding mountain bikes in the North Georgia mountains and I was excited to attempt a traverse of the state on two wheels. If you've never heard of TNGA, it's a 350-something mile route across North Georgia. Depending on who you ask, it has between 35,000 and 50,000 feet of elevation gain. It's roughly 20% single track trail and 72% unpaved. Every year in August, there is a "Grand Depart," where a bunch of crazy people m...

2020 Zofingen ITU Powerman Travel Grants Now Available for Elite Athletes

The application period for travel grants is now open for qualified US elite athletes. Grants, up to $1500 per athlete, will be awarded to 2 male and 2 female athletes to represent the United States in the Elite Categories at the 2020 ITU Long Distance Duathlon World Championship (Powerman Zofingen) in Zofingen, Switzerland. The race date is September 20, 2020. Having traveled overseas to compete, I recognize the financial barriers and lack of incentives for elite athletes. With these travel grants, I aim to make travel more feasible and provide incentive for elite athletes to participate in the elite categories of the Long Distance Duathlon World Championships. Athletes must possess USA Triathlon Elite License (in duathlon) and be eligible to compete in the Elite Category of the World Championship. If you do not currently possess a USAT elite duathlete license, you may apply for one on the  USA Triathlon Website . For more information about Powerman Zofingen check out ...
