This is the 5th annual Thumper/Break-Up and it will be the most memorable yet. Of all the course designs, this new one is the RD's favorite and is likely to be yours too. There will be navigation, trekking (running or hiking) and mountain biking. The Break-Up will require paddling, but the Thumper will not. There may also be surprise challenges for both courses. The team that completes all the checkpoints (or more than other teams) with the fastest time will win the race. There will be several checkpoints that are mandatory (transition areas), but most are not. Both courses are unsupported, you will have access only to the gear, food and drink that you have on your bike or in your pack. The Thumper will be approximately 20 miles total and the Break-Up will be approximately 60 miles total. Visit www.adventureracekansas.com for entry fees for Solo or 2-3 Person Teams.
