I guess I am sadly out of shape. Just got a trackstand ultra, and find it much harder than actually riding. After about a half hour and about 6 miles I am dying. I can get out of the trail after 10-15 miles at over 8mph avg. of real and my legs feel fine, but I get off the trainer after 30 minutes & 6 miles at about a steady 10mph & am shot. Is it the fixed resistance on the trainer, or do I just suck?
it can get really hot on the trainer, you dont have the wind to cool you down. You are also constantly pedaling. Not slowing for turns, hills, traffic signals. Also, the mental aspect of it is difficult to get past for some people.
Mechanically, make sure you dont have the tire contact knob super tightened down. I never used that blakburn, but you should have it tight enough so you arent spinning out the tire while sprinting. Also, I assume you are using a road bike. Keep those tires inflated as much as you can. Anything that can cause drag on the bike in a real life situation is exaggerated times ten on the trainer. Derailleur alignment, bad bearings, etc.
