Riverboat Series Day 5

Riverboat Series Day 5 is held in Columbus, Kentucky, on Friday, April 16, 2027, as one stop in the Mainly Marathons Riverboat Series. Five road formats are offered on the same day: a 50K (31 miles), a marathon (26.2 miles), a half marathon (13.1 miles), a 10K and a 5K, so runners covering very different distances share one course and one morning.

Because this is a series day rather than a standalone race, many entrants run several days back to back and choose their distance according to how their legs feel. If you are chasing a state on a marathon quest, the full is the obvious pick; if you are recovering from the day before, the 10K or 5K keeps the streak going without digging a hole. For a single-day effort, treat the marathon or 50K like any goal race and arrive off a 16-week build with a steady weekly long run.
