I'm clawing my way back from injuryville. My LBS loaned me a set of rollers, as there has been frost on the bayou recently. I'm about 10 sessions in and am past the scary "I'm going to fall" stage. I can even relax a bit, no more death grip on the bars or body clenching the bike.
My problem is I go straight from idle to max heart rate and have to stop. I haven't been able to go more that 6 min without my HR pegging. I can currently do ~40 to 50 mile ride on the road with no problem but these rollers are kicking my butt. I went running today just to verify I'm not having any weird cardiac issues, no problem running.
Are rollers just that tough or am I missing something? My cadence is higher on the rollers, but doesn't seem sky high. I'm in the big ring, compact double, and about midway through an 11/25 cassette.
