I have been cycling for quite some time now (an MTB - hardtail) and I intend to go for higher speeds above 45kmph (on road). I typically cruise around 38kmph (on road). I can endure my cruise speed pretty well and for very long durations about 2 hours continuous pedalling. But whenever I try to maintain my speed at something above 45kmph like trying to cruise at 50kmph, I run dry pretty fast. Is there a good procedure that I should follow to attain this goal
! - I am specific here about the hardtail mtb. Not the road bikes. ! - I have good aerobic and cardiovascular as well as muscular strength. Applying force on pedals is not the problem. Consistently putting that output for a good duration is.
