Road Cycling/High Speed Stationary Cycling. Pro's & Cons???...

When I talk about cycling, I’m talking about real cycling that gets the lactic moving, I’m talking about rides lasting 3-6 Hours long not 20 second workouts.

I know from experience performing the Dan Pfaff workout below I wouldn’t see any benefit whatsover, maybe apart from a recovery session.

Dan Pfaff bike workouts:

4x5x10s with moderate-high resistance and good recovery for 0-20m work,

3x5x20-25s low-moderate resistance and good recovery for 40-60m work,

2x3x40s with low-moderate resistance and good recovery for lactate work.

If you guys don’t ride bicycles into the hour sessions, how do you know you haven’t gained any benefit from it???..
