Members belong to age groups for races, and series of races. In the case of a series of races a runner's age group might change in the middle of the series. Two examples are the grand prix series and the performance standings. What will happen is that any points earned to date in the prior age group will transfer wholly to the new age group without recalculation. The age of the runner on the last race of the series will determine the final age group that the transitioning runner competes in. For 2007, the last race of the grand prix series is the Green Mountain Marathon and the last race of the performance standings is the Leaf Peepers Half Marathon.
