Campus Cycles Join us in welcoming Campus Cycles as presenting sponsor for the 2018 Littlefoot Sprint Triathlon!

From training and racing bikes for me, to Jill's fun trail bike, to kids bikes (and young adult bikes) for my daughter, Campus has us covered - and their service department is the best I have worked with!

Between now and race day, Campus can help you with bike repairs, clothing and tubes, a bike fit, or that all important pre-race tune-up! Be sure to stop in and check them out!!!

    The Littlefoot Triathlon takes place at Bear Creek Lake Park in Lakewood, just a mile from downtown Morrison. Please be aware that some of the map websites that provide directions will send you to the wrong side of the park, where there is no entrance. The park is easy to find, however. From C-470, exit at the Morrison Road exit. Head east on Morrison Road about a quarter mile, and the park entrance will be on your right.

    For those of you who would like to take your chances online, the park address is 15600 W. Morrison Road, Lakewood, CO 80465.

    The park gate will open at 5:00am. Park entry is free for race participants - we will pay your entrance fee. Spectators not traveling with an athlete must pay at the gate

    Once you have passed the entry station, turn right at the 3-way intersection and follow the road approximately 1 mile. Race parking will be in the swim beach lots (there are two of them). From there, it is a 2 minute walk south on the park road to the transition area in the marina parking lot.

    All spectators must be in the park, and in a parking space by the 7am start time. This is for the safety of the cyclists, and to ensure that the riders have an open road. The only road that leads to race parking is the bike course. Please be sure your spectators understand that it is important for them to arrive by 7am.
