5 miles in 29:02. 5:46 pace per mile/ avg. HR 150/ max HR 153. Below are pics of the Garmin with the total and also mile 1 and mile 5, the drop off in pace was minimal. This was in Boulder at 5500 ft altitude. This gives me an idea as to the altitude conversion... according to this there is a ~30" conversion in pace per mile between Nederland and Boulder? What would sea level be then? That ain't right.
5k split was 17:50.
Pm) 8 miles at HR 136/ max HR 146. My legs feel awesome.
