Swim course

Note that our swim course is dependent on a number factors, most importantly lake level. Typically we do not know lake level until several weeks before the race. Below is representative of what we think the course might look like but please check back around May 1 for final maps.

We will be posting the swim video for the race the week of the race.

Wet suits are allowed Water temperature is usually in the low 70s.

We will be staging and finishing on the beach in front of the pool at the Pines Resort. Again depending on lake level

Wave starts will be 2 minutes apart. Wave start order will be posted about 7 days before the race.

The last several years the Oly swim is two laps.

Instructions will be given at the swim start. Just remember, you do not leave the water to start your second lap. The start of the second lap will be marked with double buoys.

If you miss your start then please tell the volunteer you are out of order and need to start. We will review the circumstances and, if appropriate, will adjust your start time accordingly (please don’t count on your start time being adjusted and show up whenever you want).
