The original and still the best race on the volcano! These are rugged and remote races and won’t be like any you’ve run before. The 50K circumnavigates the entire mountain, mostly on the Loowit trail. It’s hard and will feel more like a 50-miler. The 25K starts out the same, but after six miles, descends from the Loowit to loop back on some fun and pretty trails. Both involve crossing what we fondly call “boulder fields”.
