For anyone counting (and assuming I copied correctly from my Garmin), that’s 10 miles in 1:23:23. Average HR – 168, Max HR 185.
It actually felt pretty good. Initially the half mile intervals felt too long, but I was appreciating them nearer the end! I may look next week to doing 6:45s. Another variation may be to shorten the recovery intervals, but then I don’t know I’d be able to pull off quite so many miles!
