I find that after a very hard ride (average 21 for 30-40 mile) my legs are absolutly trashed for the next 2 or 3 days, to the point where I can't even go on a recovery ride the next few days as with every miniscule effort (as small as slowly acclerating out of corner or going up hill so small I don't even notice on my "good" days) my legs will burn like crazy. On the hard rides I can feel strong all the way through and then the next day I feel awful.
For some background, I'm a 15 year old in good overall shape, Have been riding for about four months just started noticing this recently as I started getting interested in raceing and did a few junior races. Because of that, I started doing my rides a little harder and took more of a "training" approch to some of my rides and stopped just going for a ride. I eat well, as my parents are very health/fitness oriented (both are marothon runners, our family also does triathlons ect). If it makes a differance, my cadence is around 100-105 most of the time, drops a little for climbing.
I also play baseball and swim, I have been lifting to help with both for the past couple of years.
My cardio is in good shape, for most of those hard rides I'm hardly breathing harder than I am resting (no heart rate moniter) I think that may be part of the problem, when I'm hardly breathing hard while going 20-21 on the flat I tend to want to push it until I feel like I'm working harder
I would like to know if there is a way I could fix this, as I enjoy riding every day and I really don't like having to be off for 3 or for days. thank you for any help.
