UTMB INDEX

A UTMB Index race contributes towards every Finishers UTMB Index in the corresponding category (20K, 50K, 100K or 100M) and gives privileged access to the UTMB World Series Events or Majors.

Currently our Tittesworth Water and Ladybower Reservoir races are official UTMB INDEX races. Look out for the 20K and 50K logo’s on our event pages. They will indicate which races are registered with UTMB.
