I did the virtual challenge from the other running forum I frequent.
1 minute hill climb all out, and then they asked to look at the strava GAP and plug that time into an age grade calculator.
So in sum 50 minute run: warm up, 1 minute rep, cool down
Results: 1.4 miles, 65' climb (6.9%), pace was 6:53 and GAP at 5:06 pace. Age grade 83% with all said and done.
Oh yeah, the weather. 21 F. Cold. Cloudy, no wind.
