The Beast Series is an annual quest that will test your endurance, grit, and sanity. Each race will take you through some of the most beautiful and rugged countrythe Virginia Blue Ridge mountains have to offer.

Runners who complete all six races (within time limits) will receive a very special award. Please click here to register for the the Beast Series.

The entry fee for the BEAST SERIES is in addition to the entry for each individual race but included with the Lynchburg Ultra Series' fees. In short, if you sign up for the LUS, you'll be signed up for the Beast Series.

Eco-x produces three of the Beast Series events: Terrapin Mountain 50k, Grindstone 100, and the MMTR. You can sign up for these events right here on our website.
