Love this product — and we’re excited to share it again.

Long Run Coffee will be back with Bay Trailrunners in May 2027 for the third year!

At every event, we serve Long Run’s electrolyte-infused coffee before the run and around the campsite leading into race day. If you didn’t try it this year, you missed out. I’m using it every day now and absolutely love it.

Join us Saturday, May 15, 2027 at Skyline Wilderness Park in Napa for the Napa Wilderness Trail Runs and Rimrock 50 Mile.

Get there early, grab a cup, and start your trail day right.

it’s my job to make sure the park is left cleaner than when we found it today when picking up the last of my totes from the Remote aid station the Park Director had had reports of ribbons still out on the course so here I went already had run my 6 mile loop this morning but had to go sweep the sweepers 8 miles and about 10 flags and a couple signs were completely clean and free to go see you next year

it was very warm out there
