Marathon National Donna

Marathon National Donna takes place in Jacksonville, Florida, on January 31, 2027, and offers an unusually wide range of formats: an ultra of 110 miles, a marathon (26.2 miles, with about 300 feet of climbing), a half marathon (13.1 miles), a 5K, the 2.7-mile Pete's Bar Donna Crawl and a one-mile family dash. Entries go toward supporting a charitable cause.

The route mixes Jacksonville's city streets with oceanfront stretches where sea air accompanies you over the closing miles. Three hundred feet of gain across 26.2 miles makes the marathon essentially flat, which suits a first marathon or a time goal; count on a 16-week build with a weekly long run reaching 18 to 20 miles. The 110-mile ultra is a different proposition and belongs to experienced ultrarunners with a crew and a plan for running through the night. The half marathon, the 5K and the family dash keep the day open to everyone else.
