Track Category Upgrade Guidelines - USA Cycling
All track upgrades and downgrades are made through the Local Associations and Regional Coordinators. All track upgrades are processed using the following criteria:
Category 5 to 4: Complete a velodrome class or four race days
Category 4 to 3: Five race days and 20 points
Category 3 to 2: Five race days and 25 points
Category 2 to 1: Five race days and 30 points
(This is
how you get the points -- carleton)
Points
National championships, Category A, B, or C track race will be 7, 5,3,2,1 for each event.
For all other events, upgrade points are 5,3,2,1 and are based on an omnium of the event’s races.
Attendance at a USA Cycling Development Camp will count as one qualifying race for Category 5 to 4 upgrade. It will also count as four upgrade points for a Category 4 to 3 upgrade and three upgrade points for a Category 3 to 2 upgrade.
Additional Considerations
10-person field minimum for Category 3-5 and 20-person field minimum for upgrade to Category 1.
50 percent of upgrading points and number of times raced will be carried over to the next year. Points do not carry over to the next category.
When upgrading to a Category 1, points earned need to be from more than one velodrome.
A race day is defined as one full day of racing. A race day can include a number of events such as a kilometer, sprints or time trial, but it only counts as one race day.
Omniums will be counted for upgrading if atleast half the events on the omnium were massed-start.
Women and Juniors earn one point for every five race days when upgrading from Category 4 through Category 2.
Races exempt from upgrading are Youth races and races of more than two categories (i.e.: “A” and “B” races).
With the approval of USA Cycling, riders who are Pro or category 1 on the road may be upgraded to category 2 on the track, and riders who are category 2 on the road may be upgraded to category 3 on the track, without first having to begin at category 5 for men and category 4 for women.
