So far training is going well. Knock-on-wood, no injuries, although my right achilles does ache slightly from time to time and my calf does feel a bit stiff then. But so far it has been steady, neither getting worse nor noticeably better. Occasionally my left knee will act up a bit too, right above the patella, but that too seems contained. The shoulder is much better and I think I will survive the 2.4 mile swim, although I may have to resort to some breaststroke near the end.
I ended today's workout with a nice 1.25 mi swim. Keep your fingers crossed.
