Trail Triple Crown Marathon, Half Marathon, 10K & 5K

Saturday, April 29, 2017 • Newark, DE

Run entirely within Delaware’s White Clay Creek State Park and White Clay Preserve, a 3,300-acre park spanning from the Pennsylvania border to the city limits of Newark, the Trail Triple Crown races take place on moderately hilly terrain in the park’s mixed hardwood forest areas, along with streams and upland meadows.

Along the trail, runners can expect to encounter mostly single-track trails, the course also includes sections of dirt roads and only a few hundred feet of pavement for road crossings.

The Triple Crown Trail “Da’ Half Marathon” starts at 7:40 AM and takes runners on a course that links four trail loops with short out-and-back trail connectors. Come well-trained and prepared — the course features elevation changes from 90 feet to 350 feet above sea level.

For the half marathon, runners will make their way along six trail loops for the half marathon, linked by several trail connectors, and you’ll cross over White Clay Creek during the race. For runners in the full marathon, you’ll run the same course twice.

Race Weather & Climate

With April temperatures that average between 41°F and 66°F, springtime weather in the Newark area can be quite cool, especially at the start of the race. Come prepared for wet weather also, as area precipitation averages just over 3 1/2 inches during the month.

On race day (April 29), the average low is 45ºF and the average high is 71ºF.
