And when I check the Completions page today, @Challengers, I see that Brian Lazzaro (@brian-lazzaro) knocked off his final course this morning by running a sprightly Sweet 1600 in 5:42—congrats!
I fully expect that time to drop significantly when Brian runs it again in a track meet. His other times may drop as well, as he records more efforts with his kids, Heather (19) and Aidan (13—our youngest participant this year).
