The temperature today outside The Cyclery in Edwardsville was 95 degrees, but inside, in air-conditioned comfort, dozens of runners signed up to run Mud Mountain tomorrow morning, despite the heat. In fact, already today, a new record has been established for entries in a single day: 115 (and runners are still registering online until 11 p.m.) So, what does this mean? It means that a new record for total race registration could be set this year. But for that to happen, a lot of runners have to sign up tomorrow morning, on race day. We'll see!

Here's the breakdown, as of 5 p.m.:

Entries received so far today: 115 (a new single-day record); 86 at The Cyclery, 29 online
2010 online entries: 247
2010 mail in (and other) entries: 337
Total entries to date: 581 (a new pre-registration record)
