NEWS & UPDATES:

  • REGISTRATION FOR THE 2014 RACE WILL OPEN ON FRIDAY NOVEMBER 1st!  REGISTRATION WILL CLOSE ON WEDNESDAY APRIL 2nd 2014 OR ONCE THE FIELD LIMIT HAS BEEN MET.
  • Interest in this years race is at an all time high.  Many of the other Spring 100′s in the country have filled and we expect Zumbro 100 to grow again this year.  Please register early.
  • Not ready for the 100, run the Midnight 50 or the single-lap 17 Miler!!  The midnight 50 was hugely successful last year and met rave reviews from runners!  This is a great opportunity to get some night miles in if training for a Summer or Fall 100 mile attempt.  Don’t worry, you will still get plenty of daylight miles in as well – unless you think you are going sub-6:00!  Watch the sunrise over the Zumbro River Valley!  For those that are not ready for an ultra but want to experience the trail, the 17 miler is a great option!
  • Once again, the Zumbro 100 Mile Endurance Run will be the first 100 Mile race in the UPPER MIDWEST TRAIL RUNNERS (UMTR) WILDERNESS ATHLETE SPONSORED “GNARLY BANDIT ULTRA SERIES” – If you want to partake in the series and be in the running for the cash prize – you have to start at and finish the Zumbro 100.  Learn more HERE.  UMTR should be updating this information soon.
  • Please visit and use our sponsors – they are good people, companies and organizations that help to make the Zumbro races possible.
  • Run some and help at some – that is our philosophy, simple as that.  We are always looking for Volunteers, its a good thing to do and its a lot of fun.  If you are interested in giving a day of your time – please contact us!
  • As always, if you have any questions, please explore the site, most everything you will need you can find here, if you still have questions, please contact us – we look forward to seeing you on race day.

2013 Zumbro Recap

The 2013 Zumbro Endurance Run 100MI, 50MI and 26.2MI are in the books!  It should be of no surprise that when you have an early Spring race in Minnesota, eventually you will have one with some snow.  After a decade of snow-free trail-running in the Zumbro Bottoms this same weekend each year, it finally happened and in a big messy way. Leading up to this years...

Two Seconds with Bob Gerenz – An Interview

Rarely does a race come down to a couple of seconds – never does a hundred.  In 2012, Bob Gerenz (then, relatively unknown in the Midwest ultra scene)  put his head down, kicked and kicked again and took the win – only two seconds separated him and the 2nd place finisher.  We threw a few questions at Bob about the exciting 2012 race as he prepares...

Susan Donnelly Interview

In 2012, Susan Donnelly of Oak Ridge Tennessee once again came and conquered the Zumbro 100 Mile Endurance Run.  Susan won the race for an unprecedented  fourth straight time and kept her amazing streak alive – being one of only two people to complete all four editions of the race.  Susan will return for “number 5″ in 2013, purely for the love...
