Grand Rapids (WZZM) - The sledding hills were full in Richmond Park Sunday.
Dozens of kids and their parents all bundled up against the cold, drug their sleds up the hill and rode back down.
Winterwest also held an event at Richmond Park, the Fat Bike Race. This race is a new addition to Winterwest and it is the final race in the Fat Bike Race Series.
"I was a little concerned earlier this week," said Nate, Phelps, one of the bikers. "We actually came out and checked the course with the rainstorm, just to see if it would flow well, and we made some course corrections today because there's a layer of ice under the snow."
The Winterwest festival ends February 10th.
