What is this?

Thrilla Cross is a low-key socially-distanced Cyclocross bike race held over 2 weeks (we might extend it making it 4 weeks total depending on weather), in Bend, OR.  It’s pretty simple to participate in and  pretty darn close to a CX race, except the whole running into each other, marked courses, and friends and family yelling at you (feel free to add the friends and family component at your leisure - socially distanced of course)!!!


How does it work?

  • You can enter any of the races, or all of them.
  • The series consists of stage races. Each week will produce a podium (by gender and category). 
  • You’re racing against other riders, just not necessarily at the same time.
  • For each race, you’re welcome to do as many attempts as you'd like during the race window.  Each race window will start at 12:01 am PDT on Sunday and ends at 11:59 pm on the following Saturday (7 days).
  • Load each race course onto your device by downloading it from the race web page.
  • Wherever you start on the course is your start/finish line. So you don’t need to start your activity tracker when you start your effort. Just roll on into the course.  As soon as you are on-course, that’s your start line, and your finish line. The format of the Thrilla Cross races are you will need to do 2 or 3 laps on the course for it to count.  So don't just lap it once.
  • Track your race attempts using your GPS-enabled activity tracker or smartphone.
  • Sync efforts either by exporting a GPX file from your activity tracker or smartphone. You can also automatically sync using your Strava account.
  • You must follow the published course closely. If you deviate from the course by 200 meters or more, your race attempt will be excluded from the rankings.
  • Your fastest race attempt counts on the race leaderboard as long as you run it during the time window.
  • Race attempts must be submitted within 24 hours from the time the attempt has started.
  • Login and track your progress on the race leaderboards and activity feed.
  • The race series calculates scores for all efforts during the series timeframe. Awards will be presented for top finishers in each Gender and Category.

How is this different from any other virtual race these days?

First and BIGGEST difference. You're competing on the same course as everyone else.  Only, you’re able to ride it whenever and however many times you want. On your own! Each race takes place over a weeklong time window. Go as many times as you’d like to hit your best time. 

Second difference is the way the courses work. They’re loops. So wherever you first enter the course becomes your start finish line.  That being said, our course maps start and end in a specific place. So you’ll need to edit them if you plan to start/finish somewhere else.

Another big difference is you gotta stay 6 ft apart from all other racers!  PERIOD.  We care about you and others' safety.

So, race your butts off to win epic prizes! All you need is yourself, your bike, a GPS device, and some speed!
