Safety on Roads

  • Run toward oncoming traffic, (left side of road) unless marking directs you to the right side

  • Use shoulders when available; otherwise stay close to the road edge

  • Run single file at all times

  • Remove headphones when on roads, crossing roads, or approaching aid stations

Concerns or Complaints

If you have concerns about anything during the race, address them with Race Directors AFTER the race—never with volunteers.

WEather and STR RAces

Southeastern Trail Runs has been putting on races for 15 years. In that time, the only race we have ever cancelled was the 2020 Lake Martin 100. The race was scheduled for mid-March and about two weeks before the race, COVID “Exploded!” Russell Lands asked us to cancel the race and of course we did. We did have to move our next two races from April to June, but no other races were cancelled. We will never cancel a race unless we are required to do so by Oak Mountain State Park or a City, State or Federal Government, even if severe weather is predicted. Should there be a severe storm, with lightning, over our race location at the time the race is supposed to start, we may postpone the start until the lightning has moved away. Once the race has started there is just no way to stop it. Should a lightning storm move into the race area during the race, we ask all runners to move off ridges immediately, (If applicable) until the storm passes. Most of our races do not have cutoffs so runners will have plenty of time to finish.

Here are a few photos from the 2017 Blood Rock 100. THe white stuff is snow!

The Lake Martin 100, 2023

Saturday Morning the race stared in a narrow gap between thunderstorms. The temperatures Saturday afternoon went up to almost 90 degrees. The heat took out almost half the 100 field. Saturday night we were hit by, not one, but two hail storms. The second was BAD! It damaged every car near the start. (When I swept the course Monday morning, the south end of the course looked like someone had laid green carpet over the entire section.) As if that was not enough, before daylight Sunday morning, the rain storms hit. Between 8 and 12 inches of rain fell in about 3 hours. The small creeks that runners could step over Saturday were raging class 4 and class 5 rapids. Yet several runners finished after the storms.

The Start: Saturday - 6:30 AM Start - Between Thunderstorms.

After all that, we still had fifteen 100 Mile finishers. About 40 didn’t make it to the end. We Re-Defined “Tough Mudders!”

We are thrilled to welcome ALTRA back in 2024 as a Southeastern Trail Runs sponsor for all this years races. Hopefully for many years to come.
