I ran 40 miles in a 24 hour period. I ran 40 miles in a single run. I celebrated the 40 mile run with a 50 mile run. Now, I've completed the platinum challenge. I wrote about it in my blog here. The details:
6600 yard swim - 2:37:31 (this was a 4000 yard swim and a 2600 yard swim)
40 mile bike - 2:40:00 on the trainer
10 mile run - 1:19:03
