I finished in 3:36:52 (an average pace of 8:17/mile) and had a great time. I was 680th of 2,565 finishers and 87th of 214 men 40-44 years old.
Because I ran at a relatively easy pace, rather than chasing a PR or a Boston Qualifier, I recovered quickly.
It was such an enjoyable experience overall, I'm eager to run a marathon "easy" like this again. I've never been eager to run another marathon so soon after finishing one!
