The boys and I volunteered for the Folsom Lake Ultra Trail Race. This is a 110k trail race (a little over 68 miles). Runner run around Lake Folsom (and then some). There is an option to run this solo, or in a relay.
We were stationed at the 29.1 mile aid station in Cool, CA. Cool is a neat little country town, with trails all around. Our aid station was at a trailhead that had a parking lot and restroom. We watched hikers and horseback riders come through all day.
Trail aid stations are different from road aid stations. Whereas, road race aid stations have water, an electrolyte beverage, and sometimes fruit or an energy gel, the trail aid stations typically have a variety of fuel options. Our station had PBJ sandwiches, potato chips, potatoes with salt, oranges, banana, cola, electrolytes, and water. I am sure there were other items I can’t think of. Other stations had soup, quesadillas, burritos, etc.
The boys made the sandwiches, and then dressed in their ninja costumes and cheered/ran in the runners!
Genna volunteered with me. She is a seasoned ultra runner and I learned so much from her. She is in my running club. She and her daughter served with us.
LOL. The gorse owner needed to use the facilities. 
The boys running in one of the runners who was in a relay. The other runner is one of her running partners. They are both in my run club as well.
