Point Standings - Categories - Awards |
Points will be awarded to the top-15 male and female finishers in each category in both the duathlon and the run at each race. Points will accumulate at all three events, however you must earn points in the same category in at least 2 series events in order to be eligible for a series award. Points are not transferrable between the duathlon and the run, and they are not transferrable between categories in the duathlon such as 30-39 open division and 44 & Under Fat Tire.
DUATHLON DIVISIONS: OPEN vs FAT TIRE: If you enter the Fat Tire Division, you must ride a mountain bike or Hybrid with a minimum tire width of 1.90. If you enter the Open Division, you may ride whatever type of bike the weather and course conditions dictate. Please DO NOT switch from the open division to fat tire if we get snowy conditions at a race. Series points will not transfer between categories. Open allows you to ride a road bike if it is dry, or a mountain bike if it is snowy. If there is a chance you might choose to ride your road bike at any of the races, please choose OPEN. RUN DIVISIONS: Race results and your series age will be based on your age on December 31, 2021 to avoid the situation where a person starts the series in one category and moves into a different category in the January or February event. |
Remember, this is a winter event, and although the entire bike course is paved, there may be snow, sand, and/or ice along the route. This website will be updated approximately 2 days before each event with the course condition to assist you in choosing your bike and shoes for the event. No pre-race email will be sent. You can find a link to the course updates in the registration section. Races will be contested regardless of conditions - and if the weather warrants we may change the distances, course, or format of the race accordingly, so no grumbling - this is all about having fun in the winter.
