Running 57:03 [2] 5.7 mi (10:01 / mi) +416m 8:10 / mi
Hutton roof with Sabs en route to evening seminar on the physiology of running a sub 2hr marathon. Steady away, but was feeling the climbs as we were running them faster than I have been. Not fast, but I seem to hit a limit at fairly low pace. No pushing past it.
