Is there any problem...?

Shaun, if you have been a cyclist for 15 years then you'll know that the best way to warm up for a bike ride is to ride the bike gently. And the best way to ease sore muscles from riding is to ride the bike gently.

"They" say, as a rough calculation, that you should warm up one minute for every year of your life (so typically, before a race, I warm up for 40 or so minutes at least - I'm 42). On a training ride, I expect my legs to possibly feel muddy for the first half hour or so.

This is similar if tryig to ease sore musles. I find a gentle "recovery" ride on the flat (no hills) for about 45 minutes does wonders for sore legs caused from cycling.

I would not recommend running or jogging as a cross-training choice unless you wanted to become a multi-sporter, or unless you liked to run/jog.

At events like the Olympics, you will notice in the opening ceremony that the cycling teams do not walk round the stadium in the parade - because even walking can upset their muscles.

My three eldest sons have raced or do race while in their high school years. I write notes each week excusing them from PE classes if it involves running (including games like basketball) on Thursdays and Fridays because it messes with how their legs feel and operate for the Saturday race.

Cycling and running have no real correlation in muscle use... so the reason you mention is not physiologically grounded. The others have suggested specific stretches, and perhaps these will suit your more.

Having said all that - if you want to run - do. Thats all the reason you need.
