About
Delaware Marathon is held in Wilmington, Delaware, on April 18, 2027, with several distances on the program, from the 5K (3.1 miles) and the 10K (6.2 miles) to the half marathon (13.1 miles) and the full marathon (26.2 miles). The event has a charitable dimension, with part of the entry fees going to support a local cause.
That range of distances is the point here: a beginner and an experienced marathoner can enter the same event and each find a format that matches their training. If the marathon is the goal, count on a 16-week build with a weekly long run; if you are unsure, the half is the honest choice and still gives you a spring race worth pointing your season at.
