Ah thanks. I have hit 177 that I've seen at my highest recently. Seems to be going up little by little now that I'm monitoring it.
But honestly, I won't work on my sprint. Never really needed to. I've had guys tell me that I should but even without a sprint, they struggle to keep up when I'm keeping a good pace.
If I were racing, I would do on a trainer like I did years ago working on intervals.
Heck, I tried a few times on the trail and could hear my front wheel and bottom bracket in distress. That was in 2005 I decided any sprints would be seated. No stand and crank stuff.
And my seated sprint without side to side motions, were very controlled and hitting 32 mph on a verified flat section told me I don't really need to go faster since I'm not racing.
You're welcome.
I think adding sprint training to your base training may have an effect on VO2max. If it gets your max HR higher while maintaining the same rest HR, your calculated VO2max will be higher.
In this way, it may have positive effect on long distance endurance through higher VO2max. I also found sprint training as time efficient way to maintain cycling fitness.
