As noted, my health has taken a turn for the better. Still not sure what I had, and I am not back to 100%, but it's getting there. Whatever, I have been back on the bike for three days now. First two days was spent riding the rollers for 50 minutes each day, just working on keeping the spin smooth. The rollers bring back the smooth spin nicely after a bit of a lay-off.
Yesterday, I rode the trainer for an hour with 40 minutes of 2 min. on and 2 min. off. Was surprised with how good I felt on the hard bits and was pushing a decent gear for most of it. The goal between now and the trip to Tucson is to be on the bike 5 - 6 days/week.
