There's a lapping event Sept 29 & 30 at MAM.

Findtheline is putting it on. Cost is $150 for the day or $280 if you do both days. Depending on the turnout and how long people stay throughout the day, they run 3 groups, 20 minutes each (advanced, intermediate , beginner). As people leave and the groups get smaller, they usually just open the track up and you run when you want.

Registration is now open: http://findtheline.com/eventreg

You can find more info from that page as well.

I'll be there Saturday, but not Sunday
