You must be able to swim at least 750 yards in open water to complete the swimming leg of the Tri for the Cure – A Women’s Triathlon. The very best way to get comfortable is to practice. Beyond the monthly training plans, the free Tri Talks, and the following additional openwater swimming resources in metro Denver.
Open Water Swimming at Grant Ranch; a private lake with race buoys in place. For many, open water swimming can be one of the most challenging legs of a triathlon. Over the years, many participants of the Tri have practiced at Grant Rant/Bowles Reservoir with Mile High Multisport, LLC. This facility is a private lake with no boats and lake swimming is offered 5 days a week with weekday morning and evening options available during the week. They are open on both Saturday and Sunday mornings from May 18- September 1. Locker Room facilities on premise as well as close in paved parking. Practice BEFORE the day of the competition and reduce your anxiety on race day. Please note this is a swim at your own risk facility but there are safety kayakers available on the weekends.

The open water swim season begins in May at Chatfield Reservoir at the Gravel pond, separate from the main reservoir. Anyone can swim on specific days and times that are reserved for swimmers to train in open water. You can swim on Monday and Wednesday evenings from 4:30 to 7:00 pm and Saturday mornings from 7:30 to 10:00 am.
You do need to be a COMSA member (Colorado Masters Swim Association) at a cost of $35 for the season. If you drive into Chatfield, you will also have to pay the park entry fee. Carpooling or riding your bike will save money. This fee is well worth the money to cover liability and swim privileges at the reservoir. Even more importantly to give you experience and confidence swimming in open water as this is a very different experience from pool training! Keep your eyes on the website and your email for swim clinics in the near future. Here is the website link for COMSA.
