6 mile bike course followed by a 5k run. We have one, central transition area at the Lockport Boat Launch--a truly beautiful spot for family and friends to cheer you on! In addition to deciding if you will race the swim tri or the adventure tri, when registering, you must decide if you want to race individually or with a relay team. The system is set up so that each relay team member will register separately, but using the same team name. Once your first team member registers, the others will find the team name on the dropdown menu of existing team names. If you are the first, you will get to type in your team's name. 2-person and 3-person relay teams will compete against each other within the same tri type and gender division, but they are listed separately at registration due to the different fee schedules. Relay teams can be All Female, All Male, or Mixed Gender. The top three teams in each gender category for each race will receive awards. All participants completing the course individually will register for either the swim or adventure option (no need to enter a "team name. " For each race, the top male and female, in addition to the top three males and females in each of the following age groups will receive awards: under 21, 21-29, 30-39, 40-49, 50-59, 60-69, & 70 and over. "Recovery" food will be provided for participants after the race. Registration includes either a long-sleeved, super soft race shirt or a cool athletic towel, your choice. Safety Note: PFDs must be worn while in your boat, and helmets must be worn while on your bike. The bike course is on open roads, so no headphones/earbuds may be worn while on that leg of the race.
