Race Overview

The Coastal Delaware Running Festival takes you through Rehoboth Beach on a loop course that is about as flat as a marathon gets. The elevation barely registers. From the first mile to the last, there are no real climbs to manage and no long descents to waste your legs. What you get instead is a quiet, manageable course where your fitness does the talking. Early April here tends to be cool in the morning, which helps. Just don't let the flat start convince you to bank time too early. Run your pace.

This is a genuinely good course for a BQ attempt or a personal best. The field is smaller, which means less congestion and more room to run your own race. Registration is open, so getting in is straightforward. Sign up early for the best pricing, and don't overthink the logistics. Rehoboth is an easy place to spend a race weekend.

Loop

Start and finish in one place

This loop course sits between one and 47 feet of elevation, making it effectively flat throughout. With no meaningful net gain or loss, pacing is consistent from start to finish, and you won't need to bank energy for climbs or recover from descents. The absence of elevation variation puts the work squarely on you. Early April conditions average a high of 67°F and a low of 46°F, so morning starts should feel comfortable, though warming temperatures later in the race can factor in. The USATF-certified course suits runners targeting a qualifier or a personal best. Run even splits and resist going out too fast in the first miles.

What to expect

April in Rehoboth Beach runs cool in the morning and mild by the afternoon. You'll likely start in the mid-to-upper 40s, which is comfortable for the first few miles, but it can warm into the upper 60s by the time you're closing out the back half of a loop course with nowhere to hide. The coastal location also means wind is a real variable. Dress in light layers you can shed early, and don't let the pleasant start fool you into skipping hydration.
