Qualifying Races

Beginning with the 2015 race, we made the qualifying standards trail 100K and 100 Mile races. We have limited the number of qualifying races to the largest trail 100 milers domestically, and the largest 100Ks that are also of significant difficulty. Worldwide, we’ve included the largest races but also have the goal of geographic diversity so runners from anywhere in the world have an opportunity to run a qualifying race.

While every effort is made to ensure that this information is current, complete and accurate, WS cannot be held responsible for any loss, injury, claim, liability, or damage related to your reliance thereon. WS reserves the right to determine all WS qualifiers.

We update the list of qualifying races once a year each September and post by October 1. We welcome corrections of factual errors at anytime. WS does not receive any payment or other benefit in exchange for placing an event on its list of Qualifying Races.

An event that is not on the list cannot be used as a qualifier.
