Notes
A bit of diaphragm work helped with breathing and un-sticking whatever was going on with the right side...need to really keep after it. Cooler day but full sun didn't offer as much cooling/comfort as I had expected.
Not sure how much I trust the wrist HR but it has been consistent on steady efforts...if its accurate, i'm quite pleased with miles 2,3 and 4.
Should probably try to fix HR strap...probably just a battery issue
