The race features a 2.4-mile two-lap clockwise swim in Lake Monona, exiting up the Helix at Monona Terrace into T1. The 112-mile bike course navigates south and west through rolling hills and farmlands of Wisconsin, including two loops and spectator crowds in Verona before returning up the Helix. The 26.2-mile run course is a 2-lap loop through downtown Madison, passing Camp Randall Stadium, UW Lakeshore Nature Reserve, University Bay, and looping around the State Capitol building to the finish line.

ROKA Swim Course

Athletes will enter the waters of Lake Monona as a self-seeded rolling start to begin their two-lap clockwise 2.4-mile swim. Once athletes complete their first lap, they will stay in the water to start their second lap. As athletes make their final left turn and exit the swim they will make their way up the Helix at Monona Terrace as they run up into T1.

ZOOT Bike Course

Once athletes exit the changing area and head to their bikes they will start the 112-mile bike course by mounting their bikes and heading down the Helix. Once on course athletes will navigate south and then west before arriving at the hilly two-lap course, taking them through the farmlands of Wisconsin. Athletes are known to be met on the most challenging of hills with spectators cheering next to them as they reach the peaks. In the town of Verona, athletes are met by crowds lining the streets cheering them on as they start their second loop and then head back to the Monona Terrace. One final push up the Helix at the Monona Terrace and athletes will find the dismount line at the top.

HOKA Run Course

This legendary run course is a spectator-friendly two-lap 26.2-mile course, taking athletes through the streets of downtown Madison. On their journey athletes are taken through the iconic Camp Randall Stadium before heading toward the UW Lakeshore Nature Reserve and running next to University Bay. As you head back toward downtown, you may notice the raucous crowds cheering you on as you run around the Capitol building before starting your second lap or heading toward the finish line.

Location

City insight: Madison

Madison, Wisconsin, is the state capital, set on an isthmus between two lakes, Mendota and Monona, with many paths and a strong outdoor culture. The climate is continental: summers (June to August) are warm and humid, autumn is cool and colourful, winters (December to February) are long and cold with snow, and spring is slow. Late spring to early autumn is the best time to race, and the lakes are good for swimming in summer. Dane County Airport serves the city.
