Results have been posted from yesterday's Out of Bounds 10K race.
I finished middle of the pack, 18th out of 37. (3 seconds behind the next person -- we were doing the downhill run at the end of the race side by side most of the way, and chatting about how this is much easier on skis than on foot, but he had a bit more left at the end.)
As I suspected, I was the only person in my age group (although there was someone in M70, and I did beat him).
But I felt my victory in the one-person age group was at least somewhat earned, in that I would have been 1st place out of 7 people in the M50 age group.
