How and why the UTMB Index gets updated.
I recently completed a race, but my UTMB Index hasn’t changed. Why?
The UTMB Index is recalculated for everyone once a day, taking into account all the results received during the day, hence scores will not be immediately included in your UTMB Index. Please check again tomorrow. If your UTMB Index has not changed after 24 hours, it is because the new score is not significantly different from your existing scores to make an overall change. Please be assured, the calculation will always give you the best possible UTMB Index looking at all your results.
My UTMB Index has changed, but I haven't participated in any new races. Why?
Your UTMB Index is recalculated every 24 hours taking into account all the results in the relevant time period. As your result gets older, they will carry less weighting in the UTMB Index calculation and your UTMB Index will naturally decrease (unless you have new results coming in).
