Event Description


Weekday mountain bike racing is back in Missoula for 2021.  6 weeks of racing every Friday night at Marshall Mountain.  Lot’s of categories and a different course every week.  Challenge yourself on difficult courses and against the best riders in your category.  New for 2021 we will offer some different categories.

COVID protocols are still in affect until further notice.  This series will be a show and go time trial format, where you can start with up to 4 riders.  98 racers total per race week.  Start times 3:30pm – 7pm on Fridays.  No spectators at the venue unless you are a racer or parent (only one parent per ZTD rider).  This protocol could change over time, but this is how we will start spring racing.

I love nerding out on categories, so this years series will be no different than what you’ve seen me do in the past.  Drum role please, here are the series categories.  Each category gets a leaders jersey.  Each category will have it’s own number plate color.  For some of the weeks I’ll modify the lap numbers for each category.  That said I will not be modifying the course features.  Missoula has good riders in all categories and it’s fun to challenge yourself technically.  I’m releasing the courses early so riders can pre-ride or scout before racing.

Team and Overall Competitions

New for this season we are bringing back an overall team challenge and overall individual challenge.  You can pre-select from any team at registration.  Each category is worth the same amount of points. 1st = 10, 2nd = 9, and so on.  The overall team winners will be a diversified team.  There are no limit on number of members on a team.  For the season long individual scoring, it will be the same points you earned from your category and just put into the individual overall.  Both team leaders and individual leaders get special jerseys for the week.  Jerseys get picked up at registration (pre-washed).  At the end of the season you get to keep the jersey for the year.  If you lose the jersey please drop it off at MTCX HQ in the drop off area any day before Friday.
