XTERRA Off-road Triathlon and Duathlon

July 10, 2022

18th Annual XTERRA EX2

Escape the summer city heat and head for the mountains! Join us at Rocky Gap State Park in Flintstone, MD for the 18th Annual XTERRA EX2 Off-Road Triathlon and Duathlon.

The triathlon race course starts with a two lap swim in warm clear waters of a mountain lake and the duathlon starts with a 3.5 mile trail run. After the first segment, all racers head out to complete two laps of a mountain bike course that includes twisty lakeside singletrack, wide fire roads, smooth grassy sections, and a few rock gardens. Once completing the mountain bike course, racers transition to a 5.3 mile run that has rooty trails, smooth open flats, and a few climbs. All in all, this course is super fun and has challenged thousands of newbies and seasoned vets over the years!

Updated Course Information

We LOVE Rocky Gap and have an amazing relationship with the park staff.  Both the park staff and our team were very surprisingly notified Friday at 2pm (while we were driving up to the park) that we could not use the gorge trail and the trail had to remain closed.  We had met in-person with the park last week to confirm that we could indeed use the gorge trail during the race, but the decision was made higher up in Maryland DNR that using the trail would put the park system at added liability risk.  This decision was communicated to the park staff Friday afternoon at 2pm who in turn communicated it to us.  When we arrived at the park Friday evening, we created a new run course for both the triathlon and the first run of the duathlon and made additional modification to aid station locations to align with the new course design.  A summery of the new course is below.

Swim course – remains unchanged from previous years.

Bike course – remains unchanged from previous years, but the aid station locations are now located at mile 1, 2.5, 6.5, and 7.5, and 9.

Run course (triathlon run and duathlon run #2) – all new with a distance of 5.3 miles.  Aid stations are located at mile 0.7, 2.4, and 4.2.  Elevation gain is about 700 feet on the run and has the same mix of pavement and trail as the old course (about 1 mile of pavement total).  I think you are going to love it!  There is no stream crossing as the new course avoids the gorge completely.

Run course (duathlon run #1) – all new and is a shortened version of the main run course and has a distance of 3.5 miles with the same mix of pavement and trail as the old course (about 1 mile of pavement total). Aid stations are located at mile 0.7 and 2.4.

The XTERRA EX2 Off-Road Triathlon is one of the points series races held in the United States. Competitors earn points based on their finishing place. Racers use these points to vie for the title of XTERRA Regional Champion thus qualifying for the XTERRA World Championship held in Hawaii.

You are going to love this race venue! With its picture perfect beauty, fantastic amenities, large clear mountain lake, and challenging trail network, Rocky Gap State Park offers a stellar venue for this nationally recognized points series race. Rocky Gap has tons to do and is just a 2.5 hour drive from the Washington and Baltimore metro areas. You can make it a family weekend, with camping, a Jack Nicklaus golf course, awesome beaches, plenty of trails, and fishing – everyone will love it! Or you can make it a fun weekend getaway – there is a fancy lodge/casino on site and plenty of bed and breakfasts located right in Cumberland.

Team Relay Option

Each duathlon and triathlon relay team may be comprised of two or three racers. Each athlete on relay teams must complete at least one FULL segment of the race, either the .75 mile swim (Tri)/3.5 mile run (Du), 13 mile bike, or the 5.3 mile run. Racers will ‘tag’ each other at the bike rack where their bike is placed. For two person teams, one racer will have to complete two FULL segments and the other racer will only complete one segment.
