Parking And Transportation 

Paid parking is available near the 50K start in Aspen on the streets or the Rio Grande Garage. The Snowmass Garage at the finish line has free parking available. Free parking is also available at the Brush Creek Lot. We have arranged for an early RFTA bus to leave the Brush Creek lot at 5am heading to Rubey Park in Aspen. The first normally scheduled bus leaves Brush Creek at 5:30am and arrives in Aspen's Rubey Park at 5:48am. If you are staying in Snowmass and plan to bus this will be your best option to get to the 50K start since the Snowmass busses to the Brush Creek lot do not start running until 6am. There is limited parking at the Tiehack parking lot (25K start). There is free bus service to the Tiehack parking lot via the Castle/Maroon bus by getting off at the Aspen Rec Center stop and between Aspen and Snowmass on RFTA. Busses run continuously between the start and finish. Please check the RFTA's website for the most up to date information.
