So I may have been a little optimistic about getting to 100 miles this month. I'll likely have to put in some pretty serious miles over Memorial Day weekend to hit that mark, given the short runs this week in advance of the 3.5 mile race tomorrow. Not going with a full taper, but also not going to stick a 10k mid-week either and probably will give myself a recovery day Friday if I push hard during the race.
Did an easy run this morning, and for the third time in the last ten days did not get heart rate info. Very aggravating. Upon further reflection, I thought this might be tied to a recent firmware update for the watch. And it appears, based on the power of Google search results, that I might have correctly deduced root cause.

Anyway, there are a couple of tips on how to work around the issue while awaiting a later firmware update to fix the issue. I'm hoping they work, as I hate, HATE,
HATE running races and not having good data to review after the fact.
