Simon and Suzanne Percy, of Swim Devils and Swim Devil Masters, took over the AZ Open Water Series in 2023, after a 4-year pandemic hiatus - and the first race had to be cancelled due to the algae bloom this spring at Bartlett Lake. But the second race went off not-exactly-smoothly at Bartlett on August 19. 4000 meters, "more or less"; probably 4200 but they adjusted one of the turn buoys after our first lap, so we didn't get to 5000 after all.
I finished in 1:32:06.9. I'm not sure that kind of precision is warranted but 1:32 seems right; I had 1:35 on my watch but stopped only after getting out of the water. That put me 35/41 overall (35/43 with 2 DNFs), 17/22 men (17/24 with the DNFs) and 9/12 in men's masters (9/14 with 2 DNFs), but in swimming they lump everyone 45 and over in the masters category, and if there was a 65-69 age group (or even just 65+), I would have been 1/1. If there had been a 60+ age group, I would have been 3/3 (3/5 with the 2 DNFs). Not the best time, but not the worst, as 6 people finished behind me, and all of them were under 60. Results here for men's masters, and here for overall.
