I have been training on the bike fairly diligently for about four years now, doing about 10 hours a week. Though I didn't feel run down or unhealthy my legs were feeling a little heavy just walking around between rides. So I started taking Mondays off, usually did a 2 hr ride. This meant I was now off the bike Mondays/ Tuesdays and Friday/Saturday doing only three days a week. Funny thing is over the following three months my performance on the Sunday morning rides significantly improved.
Now if you're a young chap who recovers really quickly then this might seem weird but for us old guys managing recovery is very important.
I didn't think I was over-training before. I just felt with work and the everyday life [censored] it was too much of a physical drain. The improvement came I believe because on Wednesdays and Thursdays I was able to increase the intensity of the indoor interval work and on Sundays I was fully recovered and able to truly challenge myself again on the road.
I also increased the range of cadences I do intervals at from 75 to 85 range to 75 to 112 range.
I read somewhere that one should do most of their training over 90 rpm. I have noted on Sunday rides most weekend riders don't do this. A huge number push a big gear quite slowly. I believe this fatigues muscles at a more rapid a rate then high cadences which tend to challenge the heart and lungs a little more. So it follows on that intense high cadence intervals will be less fatiguing on the legs then low cadence intervals.
So to keep this in perspective… is a sixty year old cyclist riding three times a week at various intensities, once a 90 k over hilly terrain, twice 30 k intervals ( 160k a week ) doing enough training ?
