Five years ago, Selden set up our Toyota Siena for adventures in retirement. I have put over 115,000 miles on it; slept countless nights in the bed; moreover when the bed gets converted back into a couch, I just wheel my mountain bike in.
A good week of training - given a Monday hike with college buddies - there was no rest day this week. However, the average minutes per day went down, to let the body accept the extra workload. I managed 17.5 hours, on 172k (133k bike, 37k run, and 2k ergometer), with 4850' vertical. I also did a nice interval session, a single PT stretch session, and two strength workouts.
