Too often athletes like to ignore the messages they get from their bodies. They think exercise and training are all about motivation and discipline.

There are things you can do to speed recovery but perhaps a better approach is to rethink your training program.

For example, if you did: Sun 20 ride, Mon 10 ride, Tue 2 run, Wed rest, could you ride 25 on Thu without tired legs?
If so, how about Sun 30 ride, Mon 15 ride, Tue 3 run, Wed rest ... how would you feel on Thu with this routine?

And so on ...

If you have dead legs after a day off, there's a very good chance you should start with shorter distances and less intensity. Build up gradually until you can recover fully after a rest day. Your body will know when it's ready for more work if you're willing to pay attention to it. Pushing through dead legs isn't smart training; it's a path to injury and loss of progress. Take a few steps back and rebuild from there.
