It's a challenge to climb a major hill on a bicycle, though when you're part of a group of cyclists, maybe your endurance goes up.

You may test this theory, or one of your own, on Sunday, Sept. 27, at the fourth annual Tour for Woodside, a bicycle riding fundraiser for Woodside High School that offers a choice of three routes: 32, 55 or 100 miles.

An end-of-the-ride meal, with food from Draeger's market, will await riders at the school and is included in the ticket price.

A $40 ticket gets you a 32-mile trip, with 1,800 feet of uphill riding that includes a visit to the Pulgas Water Temple on Canada Road in Woodside, plus once around the circuit of Sand Hill, Portola and Alpine roads.

The $50 ride covers the same route, plus a trip up Kings Mountain Road, over to Alice's Restaurant and down Highway 84. The climb is 4,160 feet, considered a moderate to difficult route.

The century ride, labeled difficult, is $60 and includes the Water Temple, then a mountainous ride to the coast via Tunitas Creek Road to San Gregorio, with a return loop around, returning via La Honda and Sky Londa, for a total elevation of 8,600 feet.
