Outside vs. TR? Which is more effective?
I have been riding and racing road and cyclocross for the past five years. During that time all my training was outdoors. Now, with a new job, I don’t have the time to put in the long hours. I have switched 95% to indoor training. However, I do go on a group ride once per week. Its a “drop group ride.” I have not yet been dropped but I have struggled to hang on to the lead group (4 or maybe 5 riders).
I am struggling because I don’t have a bunch of outdoor base miles in my legs? Or is it because I’ve only just completed sweet spot II?
Any thoughts would be appreciated.
