The third set today between France's Jo-Wilfried Tsonga and Canada's Milos Raonic featured 257 points, 91 winners, and 45 unforced errors. Tsonga won the third set, 25-23 — the longest in Olympic history. The National Post's Bruce Arthur was there, watching the entire match and becoming more incredulous by the point. Here is his account, preserved for posterity. Enjoy.
Bonus: If you've never read the Guardian's Xan Brooks and his live-blog of Isner/Mahut at Wimbledon 2010, drop what you're doing and go read it. (Even if you've read it before, check it out again. It holds up extremely well.)
