A bicyclist was killed in an accident during the Climb to Kaiser race today.
It happened just before 10:30 this morning near Shaver Lake, just 2 miles north of Highway 168.
According to the CHP, the cyclist was a 50 year old man from San Diego.
Race organizers say the man was riding in a group down hill when he lost control on a curve, went off course and collided with a tree.
Despite a quick emergency response, the man died at the scene.
Hundreds of people participated in the race.
It's a 155 mile ride and requires more than 13,000 feet of climbing.
Organizers say people train year round for events like this, and it's one of the toughest rides in the nation.
