I'd only been riding again, after a 20-30 year layoff, for about 6-8 months - last July to this past January. I rode a Windsor Tourist (no lightwieght but a decent bike) on a tour in Sep/Oct - about 1100-1300 miles ( I forget). I'd gotten my average speed up to about 14-16mph depending on route/terrain. This past Spring I didn't ride from January thru April but I'd gotten back on the bike for 30 consecutive days of metric centuries in May with mostly respiratory problems, not muscle-related ones.

Accident in early July - result - minor balance issues (while walking(!)), continung back issues (re-injury and long-term injury), head issues(concussion), etc., etc.

Moving to the trike was a spur of the moment thing - well, actually, it was after I dumped a recumbent two-wheeler twice on a demo ride and my ego got whacked. No such balance issues on the trike, obviously. Immediate identification with the "I can still ride" feeling. I don't have ego/jealousy issues about bikes, per se - most of the fancier geegaws are over my head value-wise.

But I do want to get back to how I felt physically on and after my tour last Fall. I could pedal all day long, with a load, and wasn't particularly slow when unloaded - but certainly no speed demon. I guess I'm just having mixed emotions considering the "fitness setback" and the adjustment to the trike. It doesn't help that in comparison to bikes, there's far less info on the Net about actual fitness training with respect to trikes and I'm not sure just how much of the bike training information is directly transferrable.
