The Zumbro Endurance Run hosts four races simultaneously; the Zumbro 100 Mile Endurance Run (starts at 8:00 AM Friday), the Zumbro Midnight 50 (starts at 12:01 AM Saturday), the Zumbro 34 Mile (Starts at 7:00AM on Saturday), and the Zumbro 17 Mile (starts at 9:00 AM on Saturday). Each distance will have its own unique race number (unique color and number series) so runners can be easily identified by race officials, volunteers, spectators and other runners.  Additionally, 100 mile runners will be given a piece of pink ribbon and 50 mile runners will be given a piece of blue ribbon to tie to the back of their running vest, belt, hat, shorts etc. so they can be easily identified from behind (and given the right of way) by other runners. Runners who register by the deadline will have their name custom printed on their race numbers. We ask that all competitors wear their number on the front of their body on their outer-most layer at all times. Runners will be tracked coming into and out of each aid station. If we cannot see your number, we cannot track you or take your finishing time and if we cannot do that, you will be disqualified and will not earn an official finish.

Your bib number assignment can be found HERE once they have been made (about one week before the race)

Race number back, typical all distances:

The Zumbro Endurance Run will be chip timed. Your timing chip will be affixed to the back of your race number. Do not remove your timing chip. Do not bend or fold your timing chip or crumple your race number – this may break your timing chip. Your race number and your timing chip must be pinned on your outer-most layer at all times. Above guidelines must be followed in order ensure that split times and finish times are recorded. This chip is disposable and does not need to be returned.
