Heartland Series Day 4

Heartland Series Day 4 is held on July 13, 2027, in Fulton, Illinois. Five distances are offered on this day: a 50K (31.1 mi), the marathon (26.2 mi), the half marathon (13.1 mi), a 10K (6.2 mi) and a 5K (3.1 mi). Start times are not listed in our records.

Adding a 50K to the middle of a consecutive-day series is an invitation aimed squarely at ultra runners collecting distance rather than times. If that is you, the practical advice is unglamorous: eat more than feels natural the evening before, start slower than the first day, and change your socks — over a week of racing, the feet fail before the legs do.
