ABOUT QUADZUKILLA

Established in 2015, the Quadzukilla consists of four Half Marathons (a Quadzuki) on the weekend before Thanksgiving plus the four Full Marathons in the Seattle Quadzilla starting on Thanksgiving Day. Quadzuki + Quadzilla = QUADZUKILLA! The Quadzukilla allows Marathon Maniac and Half Fanatic "Double-Agents" to level up by doing up to 4 Halfs and 4 Fulls in just 9 days. ​​
