MADISON, Wis. -

Volunteers are battling the heat and elements in a fundraising event for the Boys and Girls Club of Dane County.

CEO Michael Johnson is sweating it out spending up to 48 hours on the roof of a semitrailer in the Metcalfe’s Market parking lot trying to raise $350,000.

Johnson and some of his friends from around the area are pedaling in place on the roof of the truck. The final push comes ahead of a big bike ride event Sunday.

“I’m trying to let people know about the Boys and Girls Club and the need that they have,” said Tim Metcalfe, of Metcalfe’s Market.
