Riverboat Series Day 7

Riverboat Series Day 7 is held in Vienna, Illinois, on April 18, 2027, as one day of the Mainly Marathons Riverboat Series. Five distances are on offer on the day: a 5K (3.1 miles), a 10K (6.2 miles), the half marathon (13.1 miles), the marathon (26.2 miles) and a 50K (31.1 miles).

Series days like this one are built for runners collecting states or stacking back-to-back long efforts, so pacing matters more than usual — if you are running consecutive days, the marathon or 50K here should be run well inside your limit rather than raced. If you are dropping in for a single day, the same start line still gives you everything from a 5K to an ultra, and you can decide late which format your legs are ready for.
