There's no secret that riding a bicycle is good not just for the rider, but also for the environment. With that in mind, Salt Lake County is sponsoring its annual Cycle Salt Lake week with events ranging from free bike tuneups to memorial rides to honor cyclists killed on the road to 100-mile tours.

The weeklong celebration of all things bicycle-related begins Saturday with the Live Green Festival at Library Square and a mountain bike tour along the Bonneville Shoreline Trail Sunday at 2 p.m.

Organizations such as the Salt Lake Bike Collective and UTA will sponsor events during the week.

While most of the week will focus on recreational or commuter biking, there will also be something for the serious cyclist.

Criterium races will be held Tuesday at Rocky Mountain Raceways and Wednesday at the DMV training course in West Valley.

On Saturday, those wishing to test their legs can ride the Salt Lake Century from the State Fairpark out to Antelope Island and back.

Got Legs?: There is no shortage of long bicycle rides you can take and also help out a good cause. Most of them involve a lot of miles, a lot of smiles and some of the best company you can find on two wheels.

Things really get rolling with the charity rides on June 2 when several hundred women hop on their saddles for the Little Red Riding Hood ride. The women-only ride benefits breast cancer research at the Huntsman Cancer Institute. While the 100-mile option is the most popular, there are also 38- and 68-mile options starting in Wellsville and touring Cache Valley. Visit BBTC.net for more information.

A week after that, the Tour de Cure ride rolls out from Brigham City with 25-, 60- and 100-mile rides benefiting the American Diabetes Association. Tour de France winner Greg LeMond will be part of the June 9 ride. Call 1-888-342-2383 or visit tour.diabetes.org for registration and team sponsorship information.

The two-day MS 150 ride will be held June 23-24 and rolls out of the Cache County Fairgrounds with proceeds helping out the Multiple Sclerosis Society. Businesses and individuals can get involved by calling 424-0113.

Racer's update: Last weekend saw wet and wild weather test racers in a pair of events. Bart Gillespie dominated the mountain bike field throughout the 43-mile course at the Showdown at 5-mile Pass in the hills above Lehi.

A little farther north, the boys from Sienna Development/Goble Knee Clinic endured 60 miles of sand blown into their faces and left Antelope Island with the desired results.
