What is the Mixed Duo Ranking?

A ranking dedicated to male/female pairs, based on the combined individual performance.  

There are two formats:
1. Mixed Duo H/F MDS ULTRA Ranking: 
Each member of the pair runs solo, at their own pace. The individual times are added together to establish a specific Mixed Duo ranking, reserved for male/female pairs in the MDS ULTRA  

2. Combined Mixed Duo Ranking (Ultra 100 miles + Legendary)
This overall ranking is intended for male/female duos who participated in both events:
- MDS Ultra 100 miles (January 2027)
- MDS Legendary (April 2027)
The times of both members are added together across the two races to establish a final combined ranking.
