Isle du Bois

ISLE DU BOIS – Saturday December 5, 2015 – Pilot Point, Texas

The Isle du Bois Trail Run occurs on the sweet DORBA trail system within the beautiful Isle du Bois (“Island of the Trees”) Unit of Ray Roberts Lake State Park located 55 miles north of downtown Dallas. This park resides within the North Texas Horse Country which is one of the largest concentrations of horse ranches in the United States. As you drive towards the park you will encounter some of these amazing ranches and often see horses galloping about.

The course itself contains a short segment of wooded double-wide paved trail before you get dirty on some muscle varied single-track within the mostly wooded terrain. You will experience sections of trail that allow you to kick it up a notch as you flow along some well groomed trail, and others that will required focused concentration as you work a short yet fun leg-awakening climb, or dance over and around sections of scattered rocks that will bite if you aren’t careful.

Midway through the clock-wise loop, you will enjoy some great views of Ray Roberts Lake and you may even see some white-tailed deer that often scamper throughout the park.

*Isle du Bois is also part of the EBA High-5 Challenge Series and Texas Trail Running Championship Series!

DATE: Saturday December 5, 2015

DISTANCE: 55 km, 36 km, 18 km, 5 mile

**IDB 2015 is a Go! but we have had to adjust the course and race distances.

Here’s why.

All of north Texas received huge rains this Spring that filled all our lakes (yeah!) but it also caused lots of flooding. Isle du Bois state park just opened up at the end of September because of the high water levels. The park is looking great once again!

Unfortunately the high water levels impacted  a section of the trail system (Loop E) which had been part of our course and will require significant assessment, trail re-work, and paperwork. I don’t expect Loop E to be ready for our race in December so this year we will have an adjusted IDB adventure that will be equally as fun.

This year’s adventures will include a 5 mile, 14 mile, 23 mile, and 52 km scamper!

Yep, our race distances are odd and we kind of like it that way! :) While the distances may be wacky, they are measured with a professional measuring wheel = pretty darn accurate.
