5-team RUNNING MATCH challenge on Tribesports

Options
Wanted to let y'all know about a 5-team RUNNING MATCH challenge on Tribesports.com right now. We have an international group of 77 or so runners already competing to see which team can reach 4219.5 km first (don't ask me how they came up with that number). Anyway, all you need to do to join is to sign up for a free membership at Tribesports.com, then search for "5 team running challenge". There are a lot o' great running (and other physical) challenges there, too but this is the one that has caught my attention. Feel free to join us and make things more interestingly competitive! Thanks.
