Adapts to your fitness, schedule & recovery every week.
Prepare for a crisp 10-15°C morning start, followed by midday peak temperatures of 22-27°C with high sun exposure on the run. Use the lakeside shade sections of the run to stay cool, and consider keeping a sponge or ice in your kit to manage the midday heat.
Fuel & hydration
On the technical bike course, consume your calories and fluids on the straight, flat sections rather than the 48+ turns. Use the aid stations at kilometers 26, 51, and 74 to stay hydrated, and aim for a consistent fluid and electrolyte intake to counter late-day humidity.
Pacing
Avoid over-surging on the continuous rolling hills of Dane County, maintaining a steady power output on the false flats. Save matches for the run, which contains 137 m of punchy climbs where conservative early pacing pays major dividends.
Gear & logistics
Utilize the unique indoor parking garage transition to keep your gear safe from overnight rain. Arrive early to navigate the multi-story helix ramp safely, and utilize the Alliant Energy Center shuttle to bypass limited downtown parking.

Where are the aid stations located and how should I fuel on the Wisconsin 70.3 bike course?
Bike aid stations are positioned approximately at miles 16, 32, and 46. Because the technical terrain features 48 turns and constant rolling hills, you must plan your drinking and fueling strategically during the flatter, straight sections of Dane County's roads to maintain safe bike control.
