Brooklyn Duathlon

Race Start Time and Location:

On 4/11/26, NYTri is coming to Brooklyn to host our 37th Annual Spring Duathlon in Prospect Park. Prospect Park is always a special place for us because we are from Brooklyn! In 2024, we have added the entire outer park look for your second run, all 3.3 miles (5k). We are racing the same course once again this year. Your final lap of the run will be around the big loop completing all 3.3 miles, with a total of 140ft elevation gain. Be ready because the hill to the Grand Army Plaza is no joke!

Here is what you can expect on race day. At 7:30 am the race will start in Lincoln Field by the triangle grass area by the Well House Dr (E Lake Dr and Lincoln Rd entrance).

Run #1 beginning at 7:30 am is a fast loop around the park’s inner circle. Athletes will set out along East Dr and make a left through Center Dr, where you will cut across the park, exiting west side. With little gain in elevation you’ll head around Prospect Park Lake where you will pick up speed as you head in for the bike.

The bike route consists of 3 loops totaling 10 miles around Prospect Park Drive. As athletes make their way up to the Grand Army Plaza you will encounter the full PP hill on the front end and a HUGE downhill on the back of each loop. After 3 of these loops make sure you save energy to take on the same course for the run!

Run #2: The final leg of this course! Athletes will run the entire 3.3 mile PP loop. Finishing the run course with a 140ft+ elevation gain. Athletes will cross the finish line at the same place we started, in Lincoln Field.
