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

I’m referring to ESTI’s message in post #18 which doesn’t state the duration that particular “past forum member” used for his bike workouts to train his 200m runners, not Pfaff’s group.

Pfaff’s group (IMO) will not gain/enhance any of the qualities I mentioned in post #20 doing such small amounts.
