I can see myself buying a power meter in a few years, but right now I am still enjoying the idea of getting on my bike and just riding.
Some good advice for training rides on the road bike: Then set about increasing your average wattage. Mr. Vande Velde does this by punctuating rides with five minute “power bursts,” dropping into a low gear, pushing his pedals as hard as he can, his wheels turning at his top sustainable watts and barely 50 revolutions per minute. In the next five minutes, he’ll click up into an easier gear, pedals whirring at low watts and about 90 r.p.m. (which any recreational rider should be able to maintain). Then he’ll repeat.
