The Jay Challenge
The Jay Challenge is a combination adventure race and triathlon that occurs yearly in and around Jay. It is a three-day event comprising a kayak trip from the northern to southern end of Lake Memphremagog, a run over rough terrain and of mountain biking. It claims to be "the largest offroad stage race in North America", with 700-1000 racers each year. There is no cash prize and no sponsor. The course record was 19 hours and 20 minutes. In 2007, the Jay Challenge was reduced to the running portion, and temporarily re-titled "The Ultimate XC Challenge." There were participants from 34 US states and 3 countries. In 2008, the Ultimate XC Series expanded to three ultra-running races which included Quebec in June, Jay, Vermont in July, and Moab, Utah in November. The last running of the Jay Challenge was in 2008. The Vermont edition of this race series is a "marathon" and an "half-marathon." The course is almost completely on private property and almost 100% trails. The trails are rugged and muddy and include a variety of brook running, river crossings, steep hills, technical descents, bushwacking, and a sand pit. The race is limited to 400 for the full race and 200 for the half. Most runners who complete the full race take 2-3 times as long as their best times for a road marathon.
