Thousands of athletes came to Madison's streets and lakes on Sunday for the annual Ironman Wisconsin competition.
The grueling day starts with a 2.4 mile swim followed by a 112-mile bike ride, and of course, a marathon.
Athletes of all backgrounds imaginable competed, including a special pair that crossed the finish line together this year.
The Pease brothers, Brent and Kyle, were out on Sunday morning among the sea of swim caps ready to lap Lake Monona.
Though they were two of many, they were easier to spot than most: In a current made choppy by the freestyles of 2,500 swimmers, Kyle, who has cerebral palsy, was out of his chair and racing in a kayak with brother Brent as his personal tug boat.
Now fast-forward four hours to mile 45 of the bike route.
That's where you'd find Brent, pedaling enough to push both Pease brothers
But this story isn't just about any of the bikers or the runners rounding the corner of Dayton and Henry streets.
