Prepare for IU Health 500 Festival Mini-Marathon

A plan built from your answers and your race date.

The 500 Festival Mini-Marathon takes place in Indianapolis, Indiana. The course is fully paved and urban: it starts downtown, heads west across the city, then turns back toward the center for the finish. The terrain is fast and the atmosphere is that of a large spring road race with deep local support.

What sets the race apart is the Indianapolis Motor Speedway section, where runners complete a full lap of the Indy 500 oval on the track surface. The Mini-Marathon has historically been the largest half marathon in the United States. A 500 Festival 5K runs alongside it for those who want a shorter distance. Registration is open.

The formats

2 formats on the program.

When to start

A build for this distance usually runs 10 to 16 weeks. Counted back from race day, that puts the start somewhere between January 11, 2027 and February 22, 2027.

These ranges are working conventions, not a research finding — no trial has compared plan lengths against each other. What matters more is that the plan was built for the weeks you actually have, rather than shrunk down from a longer one.
