The Cemetery Island Open Water Swim will take place in Canyon Ferry Lake, 20 miles east of Helena, Montana. The 5K and 1-mile races will both start at 8 am MDT on Sunday 8/29/27 from the Cave Bay Day Use Area. The 1-mile race will be an out and back route, whereas the 5K route will go out around Cemetery Island and back to Cave Bay. The event is limited to 100 competitors.
Goals: The event provides an opportunity for open water swimmers to test their mettle with an around-the-island route in Canyon Ferry Lake. The race also serves as a fundraiser for Aspen Adult Services, an organization that provides enriching services to developmentally-disabled Montanans. Money left over after the bills are paid will be distributed this way: 80% to Aspen, 20% to be saved for next year’s race.
Packet pick-up: Times and location will be determined.
Directions: The race site is 20 miles east of Helena. From Helena, follow Canyon Ferry Road (Highway 284) out to the lake and over the dam. After crossing the dam, continue for 2.25 miles. The turn-off to the Cave Bay Day Use Area (and Kim's Marina) is a few hundred yards past mile marker #11. From the turn-off it is a short drive to the starting and parking areas.
Spectators: Drivers can drop off spectators and/or competitors in the starting area, before parking nearby. The pavilion is a good viewpoint for spectators, and there is another higher vantage point on the opposite side (northwest side) of Cave Bay that can be accessed by hiking less than half a mile from Chinamen's Campground. Don't forget your binoculars!
There are two campgrounds within a mile of the race site - Chinamen's Campground and Court Sheriff Campground. Reservations for campsites can be made through recreation.gov. Court Sheriff is better suited for trailers because its roads are paved.
Registration: Early registration runs January 1st through July 31st: $45. After that the price goes up to $60.
Age group divisions for both men and women: 13-19, 20-29, 30-39, 40-49, 50-59, 60-69, 70-79, and 80+ . . . Results will be posted on the race website within 24 hours after completion of the event.
Important Safety Information
Preparation for an open water swim: It is up to you to train and make sure you can safely swim in open water before participating in the race. The transition from training in a pool to swimming in open water (waves, wind, sun, cold water, no line to follow) is challenging. Please be sure you have swum in open water at least a few times before participating is this race.
Safety: We will update racers on any current precautions and requirements on race day. Be prepared for changing weather conditions, and prepare accordingly. There will be several race monitors in motorboats and kayaks around the perimeter of the route. Hopefully a Lewis & Clark County Search and Rescue boat will be present as well.
Pre-Race meeting: All swimmers are required to attend the pre-race meeting in the starting area at 7:30 am to learn about water conditions, sighting on the course, emergency procedures, etc.
Swimmer Identification: Swimmers will be required to wear the cap marked with their number (included in race packet).
Weather and Air Quality Conditions: We will monitor the Air Quality Index (AQI) in the days prior to the event and make any necessary announcements. Please check this Runsignup website for updates. We will check the AQI at 5 am on race day, and communicate updates via email and social media. Here are the guidelines we will follow:
AQI 0-150: No changes to event. AQI 151-180: All athletes will be allowed to compete in the 1-mile race (no 5K option will be available). AQI 180: The event will be cancelled for the safety of athletes, spectators, and volunteers. Event personnel will be on site as a secondary communication point that the race has been canceled.
