Curious what the Nova Marathon course will be like?  Here's a power file from Dave's pre-ride on 3/15. 

The course consists of 5 laps of 14 miles each.  Each lap is the combination of the sport, expert, and long loops at McDowell Mtn park near Fountain Hills, AZ.  The pre-ride was 3 laps; the 3rd laps is marked up to show the sport, expert, and long loop sections.

It rides like a XC course, but at 70 miles & 15 loops...there will be some dizziness ;)
