Dave & Ally from the XL Morning Show are gearing up for Thursday when they are hitting the treadmill at 3:30 a.m. on Friday, May 4th for Run the Mill at Bozeman Running Company to support the Cancer Support Community.

Thanks to XL Nation and Madison River Propane (who stepped up and contributed $2,000) Dave is going to join Ally in yoga pants in their 107 minutes on the treadmill.  Which brings us to our big question, whose butt is whose?
