Last year's was sometime in July and I think this would be epic suffering. The blisters on your feet alone would be worth writing about.
No wetsuits, no fins, no shoes. Barefoot on the sand and swimming with what ya got.
It's 8.5 miles from start to finish with 4000 yards of swimming in 4 sections. The fastest times I've seen are 1 hour 37. Jeeze that's fast.
Could be fun?
