The LOST Race

& LOST Mile

August 19, 2023

1 Navy St (LOST Mile)
1 Maple Grove Dr (LOST Race)

Oakville, ON, Canada

The LOST Race is one of Canada’s premier open water events and is hosted by the Lake Ontario Swim Team, a non-profit, volunteer run organization founded in 2006.

The LOST Race is a fun, inclusive and competitive 3.8 km (Ironman distance) race in Oakville, Ontario, Canada.

Oakville has become the top spot for open water racing in Lake Ontario, and the LOST Race, which began in 2008 with just 8 swimmers, has grown to over 200 swimmers each year!

The route is a point to point route and is safe and fun. It is also exceptionally scenic as it passes by one of the most beautiful neighborhoods, with some of the most spectacular and expensive homes in Canada!

The majority of participants are just regular swimmers that are up for a good challenge, but over the years there have also been some pretty amazing swimmers compete too. There’s been tons of triathletes (Ironman especially), NCAA and Canadian Varsity swimmers, Olympians, people who have swum the English Channel, around Manhattan, around Key West, the length of Tampa Bay and numerous other marathon swims around the world… and of course there are even a select few who have swum across Lake Ontario!

Starting in 2016 we also started “The LOST Mile”! A bit shorter for those that haven’t worked up to the 3.8 km distance or a bit faster for those that want to do a 1 mile sprint! Either way there is something for everyone and both are a lot of fun!

So join us for an epic morning race, splashing around in one of the best open water locations in the world!

Temperature

While the conditions have remained relatively stable over the history of the race, the biggest variable is by far temperature.

Lake Ontario is a large and very deep body of water and in the summer months is subject to "rollovers" where the cold water from the bottom of the lake is brought up to the top of the surface of the lake, dramatically reducing the temperature. This can happen overnight. Typically in mid-August when we hold the race the temperature is more stable as more of the lake has warmed top to bottom. As of 2018 we have moved the race back a weekend in a hope to benefit from statistically higher water temperatures. In the 10 previous years of the LOST Race we have had 2 years where the temperature has dipped below 55F/13C. In both of those years we offered a shortened version of the race. Typically the lake temperature in August is between 60F-70F (15C-21C).

Conditions

The conditions on Lake Ontario can vary year to year and over the history of the LOST Race we've seen a bit of everything. While there have been a couple years with some waves typically the race has been flat and smooth. The water is almost always clear with high visibility. Some years there has been a slight positive current aiding swimmers.

Race Cancellation

In the unlikely event that we have to cancel the race for safety reasons (storms, water temperature, rough water conditions, etc) we will unfortunately not be able to provide refunds as all of our costs are paid upfront (insurance, timing system, swag, medals, permits, etc). Naturally this would be our last choice, but we take the safety of our swimmers very seriously and is our top priority.

For similar reasons, like most races, we are unfortunately unable to issue individual refunds for any reason.

Safety

This is our top priority. So if you find that we tend to err to the side of safety, this is why. Realistically what this means is that if there is significant danger of any type we will cancel the race… or if we feel that for any reason you may not be able to safely complete the race, we will ask/tell you that you must abort the race. Naturally we want you to be able to complete the race and we will try our best to accommodate you, however there is a 2 hour cut off... but… it is a rough cut off (for the LOST Race, the LOST Mile is at the discretion of the on-water crew). Meaning that it depends on the conditions. If it is a tough year and everyone is much slower, then we will take that into account, but by the same token if it is a rough year we may make the cut off shorter too. Open water swimming is not an exact science, we balance: wanting to see you finish… with safety to make the call.

Prizes

We award prizes for both the LOST Race and LOST Mile. We recognize the top 3 swimmers in 4 categories for each event. The categories are: Male Wetsuit, Female Wetsuit, Male Non-Wetsuit, Female Non-Wetsuit. The 4 winners in both the LOST Race and LOST Mile will also have their names engraved on a prestigous trophy!
