A simple mountain biking technique to go faster while saving energy!
Often there is not enough detail in mtb advice or it is flat out wrong. This is an example of not quite enough detail. When I first started riding I was taught to rest on the descents (by coasting) to save energy for the climbs. This is partially true but it leaves out a Huge speed adding and energy saving technique. Won’t you like to complete your ride in less time while using less energy?!
The technique is simple, pedal some downhills and rest on the uphills! How is this possible? On sections of trail that are rolling (short downhill into short uphill, possibly repeated multiple times)as you crest the hill continue pedaling over the top and down the downhill then coast the uphill and repeat! It takes way less energy to accelerate from four miles an hour to 15-20 mph than it does to maintain ten mph uphill.
One reason I quit racing cross country years ago was it was frustrating being held by riders who were fitter than me but seemed to lack this seemingly common sense skill as well as riding skills. On one rolling section of trail at the Iron Horse Classic in 1994 I was able to maintain what felt like 20 miles an hour over a section of 12-15 rollers without pedaling (after the first downhill) in practice. In the race a physically stronger but less skilled rider was in front of me in this section and we managed about 10 miles an hour while working our tails off! Frustrating to say the least! The ride in front of me was only looking about 10 feet in front of him (aka looking down) so he braked on the descents and then pedaled the uphills and repeated! In practice I simply pedaled down the first downhill and pumped the rollers to maintain 20 and have a lot of fun! Unskilled riders in race kill fun (and waste a lot of energy).
If you aren’t clear on how this work I will break it down for you. Let’s say you and fellow rider both crest the first hill (in the series of rollers) a little out of breath at four miles an hour. You decide to rest the dowhhill by coasting as soon as possible while your riding buddy sneaks in a few pedals. The hill makes you accelerate from four mph to eight, you have doubled your speed! Meanwhile, your buddy accelerated from four to 16 or 20, pretty easy to do with a few pedal strokes on a downhill. Now, yes, at the bottom of the hill he is still a little out of breath and you have recovered but, he is going more than twice your speed! (and he is already quite a ways in front of you). Now for the uphill, you attack it (because you have recovered) and manage to maintain eight miles an hour. Your riding buddy (being still out of breath) coasts up the hill and slows from 16 to 11, reaching the top of the second hill recovered, ahead of you and going much faster into the next descent (where he will just pedal once or twice down to double your speed again.
In short,when possible Pedal the Downhills and Coast the Uphills! (on certain uphills, obviously this doesn’t work on 1,000 foot climbs, although it still will be faster for the length of the descent and the first part of the climb).
