With race season finally here, it’s time to queue up your DVRs and clear your calendars to track the biggest races of the year. But unlike baseball or football, there’s no one league with one schedule to follow all year. In triathlon, you have to look at the Ironman schedule then the Challenge schedule, plus the World Triathlon schedule and the XTERRA schedule —and then there are exciting new events dropping seemingly every week from Super League and the PTO. As if that wasn’t enough, you then have to use your triathlon deduction and sleuthing skills to figure out which events will have the most competitive start lists and how to watch them.
It can be exhausting–and you’re not even the one racing!
So on this page, we’ve compiled our calendar of the biggest triathlons of the year and how to watch them. (A warning: It’s likely to be updated and change as pros’ schedules change, so bookmark this page for easy reference as the season goes on.)
