Here's an all-on-foot (plus public transportation) 2-5 hour race in downtown Portland. It is one of those wacky races where you run to checkpoints and then do some Survivor-esque challenge. You are given a new Blackberry phone to use during the race. Sounds like a fun way to get some running in with a friend! Plus there are really good prizes!
