Tue 7/10 - PM 85 minutes plus 24 minutes in Walden

Planning on going longer today, but the 90 minute barrier seems to be about my limit. Not overly tired, although the pace was quite easy at the start. Gradually picked up until about the hour mark before backing off. Right calf somewhat stiff but for now at least, the threat of a full-blown strain seems minimal. The pond is now officially tepid, still refreshing but not bracing like it was last month.
