With the huge success of Herdy"s we have added Syderhs Back to Frontyard Ultra as the newest backyard ultra for Ultra Series WA. Its Herdy's but in reverse, same amazing location at Herdsman Lake however at the much cooler time of year in May.
See, runners tackle a 6.71k loop on the hour, every hour until the last person standing. Everyone that times out on a loop or fails to continue on, is a DNF. 24 hours of 6.71k = 100 miles.
