PR to the spring 45:14 (only 3 miles, 2100 vert). Thought I might get a RT PR but lost my daylight and had to pull back. 3 min slower than RT PR (5 min slower down). Fun to move fast uphill.
1.5 WU, 6 x 400 at 5.50mm, 1 x 800 at 5:50mm, 1 x 800 5:30 mm. .75 mile CD. Probably need to work up to 800's+ on my splits. Dripping sweat. Good workout.
