Spencer Paxson’s #TallyTuesday

We’ve been keeping up with Kona Bikes mountain biker Spencer Paxson and his #TallyTuesday where he runs through the numbers associated with being a professional mountain biker.

First up, he’s tallied up the difference of a question both him and us get a lot, “How do power demands differ between each cycling discipline?”

Here’s a snapshot of what he found.screen-shot-2016-10-31-at-3-31-31-pm

 

Above are his stats and number to compare from MFG Cross, Whiskey Off Road Marathon XC race and a UCI World Cup race. As you can see each style of race demands his system differently. Paxson told us, he relies on the technology of Stages to give him the data he needs to so so training can be tailored for the future.

Next #TallyTuesday question:

If Spencer only lived on ClifBars, how many would he need in order to break even on calories burned during a season of training and racing? And, what’s Spencer’s ClifBar mileage?

For a roughly 700hr season over 240 days, that’s about 1,500 bars assuming ~200 calories per bar. But luckily one ought not eat to replace during exercise, otherwise he would be eating 1 bar every ~4 miles, or 2+ bars per hour and Clif would run out of food to sponsor athletes with.

In practice, at an avg. burn rate of ~440cal/hour and overall average speed of 9.3mph (mountain biking is slow!?), Spencer figures he only need ~1 bar/hour, yielding nearly 22 miles per Clif Bar.

 

Back to watts on #TallyTuesday: How much would you have to pedal to power that toaster? It’s Gadget Power vs. Bike Power.

Here at Stages Cycling it’s easy to say, we are obsessed with power. However Spencer Paxson may be biased but he agrees.

“We modern cyclists are obsessed with our gadgets, which in turn gives us inflated egos, especially when they tell us how much power we produce on the bike. Think you are powerful? I bet you would be hard pressed to keep just your devices charged for a year. If we didn’t have the electric grid to keep our suite of phone, laptop, Garmin, internet/modem devices charged you’d need to come up with around 13 kilowatt hours to run them for a year. That’s equivalent to about 650 hours at 200 watts, or in my case, a decent season of training and racing.”
