Notes
COMMENTS: Officially a "10K", but my Garmin clocks it at 6.5 miles (= 10.5 km). It was a small and kinda disorganized race, so I'll believe my Garmin. (Last year, apparently, their "10K" was 11.5 km...)
Tried to maintain a 10 minute-mile pace, and pretty much did. Heart rate shot up briefly in the first mile, but other than that it stayed pretty firmly in the 162-180 range, which I think is acceptable for a race. Splits were pretty even (sped up a bit at the end).
