Best places to watch

Swim: Along the Lake Woodlands Pkwy Bridge just East of North Shore Park. Also, along the canal between Lake Woodlands and the swim finish (best accessed from the stairs down to the waterway off Grogan’s Mill). At 5 a.m. the transition area opens and at 7:25 a.m. the age-group rolling race starts.

Bike: The streets and neighborhoods are heavily congested during the bike portion of the event. In order to avoid getting stuck out on the course, the best option for the bike start and finish is along Lake Robbins.

Run: Along the waterway (3 loop course), especially near the restaurants close to Waterway Ave and near the transition area. No tents are permitted on the waterway, however North Shore Park is a good place for families/kids mid-day.
