Thunder Rock 100


The route is a point to point course mostly single track, double track and gated forest service roads in the Cherokee National forest in remote eastern Tennessee. One hour drive east of Chattanooga. The average high is 77, the low is 51 and 4.3 inches of rain are expected for the month of May. This is in the rainy season and it is common to get the bulk of the monthly rain in just a few storms. What you really want to know is what are the chances of sun. %Sun is the percent of time that the sun touches the ground between sunrise and sunset. The average in May is 65%. There is 16,100 ft of climbing, with the biggest climb coming just after crossing the 150 foot wide Hiwassee river at mile 80, a 2,200 foot climb over 3.9 miles. We decided on a noon start for several reasons: The most technical sections are at the beginning during the light of day, immediatly followed by the least technical, best at night. This ensures a unique level of equality forcing everyone to run through the night. Most top runners do not get this treat. This noon start also allows everyone to get a good full night sleep and get completely hydrated, fueled, and all normal bodily functions properly executed before the start. Runners can expect 15 aid stations with the longest distance between being 10 miles. There is a strict 30 hour cutoff time and we require all runners to have completed at least one 50K trail race.

    Will there be a Thunder Rock 100 race this year (2015)? If so when is going to be planned? I hope so, I am a local to this area.

    Thank you,

    Do you have a refund policy on the Thunder Rock 100. I am planning on signing up for the race, but may be reassigned on business to Europe before that time. I will know by end Feb. If I singed up and pulled out then, would I get a refund, if only partial?

    I am doing this race for the first time this May, and have no clue what to expect! Any clues/tips/etc would be greatly appreciated.

      Lauren, first and foremost I highly encourage you to thoroughly read both the Runner Guide and the Crew Guide for the race. Next, I suggest that you join up with the Facebook page for the race if you have not already and ask some of the other runners to share their tips with you.

    I am running the race without a crew and I noticed that drop bags may not be returned by the end of the race and will end up in your warehouse . I will be able to stay at the finish but will be difficult to find your warehouse.
