FROZEN RACE, GETTING HOTTER

The first Arrowhead 135 in 2005 featured a dozen racers. It has grown steadily and this year had participants from 27 states and five countries. They use custom-built snow bikes or pull sleds while walking, running or skiing along the Arrowhead snowmobile trail. Racers, who paid a $190 fee, started Monday at 7 a.m. and had 60 hours to finish.
