First cars and motorcycles, now bicycles and feet. Another fitness event is coming to the Circuit of the Americas. HITS Inc. will host a slew of races at the track on Dec. 14. The lineup includes a Friends & Family Mile, a 5K, 10K, half marathon, marathon and sprint duathlon. A health, wellness and fitness expo is also planned. HITS stages running festivals and triathlons around the country. The December event will mark its first Austin event. Registration is open at HITSRunning.com. Prices are $10 for the mile, $20 for the 5K, $25 for the 10K, $65 for the half marathon, $75 for the marathon and $60 for the duathlon until Sept. 13, when prices increase. They increase again Dec. 8. "Austin is a hub of motivated, receptive athletes and we are thrilled to begin this venture there," HITS Race Director Mark H. Wilson said in a press release. Officials with Holland Racing announced last month that they will stage bicycle races and a public bike ride at the track Aug. 31-Sept. 2.
