Brief background: I’m 50. Have been cycling and racing for decades. Live in an area where riding outside all year around is easy. Until three week ago when I started TR I would generally ride between 8-11,000 miles a year; race around 30-40 events a year, mostly sanctioned but many unsanctioned events. I’m a Masters/Cat 2 nobody on the road and quit mountain bike racing before they went to the current ranking system. Prior to cycling I was an NCAA div 1 athlete. I’ve been coached, followed plans outside with out a coach and most seasons just do the Ned Overend training method. Here’s my take on the main difference between training on a trainer and training outside:
Increased muscular or strength endurance. It doesn’t seem to matter what kind of workout I do the fact is keeping constant pressure on the pedals increases muscular endurance. The lack of micro breaks has been nothing short of eye opening for me.
Increased hip recruitment. I don’t know why. I feel it’s closely tied to number 1 above. But the fact is the muscles used to bring the foot over the top, drive it forward into the main power phase of the pedal stoke are way more engaged on the trainer.
Increased dehydration. If not careful of coarse. But, in general, depending on fans, temp and workout, etc…I go through 2-3X the water compared to outside.
1 hour on the trainer is more like 2 outside. At least for me. I’m comfortable saying it’s at least 1.5-2 for most. No way 1 hour on the trainer=1 hour outdoors!
Anyways, this is nothing new to most of you who have had to use a trainer to stay in shape through out the winter. For those new to indoor training or those who remember transitioning are there any further noticeable training affects I might experience? Thanks.
