No pulling riders in CX. Everyone gets to suffer their alloted time
. Thats why we try to match skillset/size by race, albeit not always a perfect mix but close enough for the officials to keep track.
Fields are much larger than in the past and nationally its become a more focused discipline for a lot of riders. Thus why you see USAC formalizing Categories (and for those old-school A/B/C self-select fellas, the real reason we need to "formalize" our own races a bit more than a handful of years ago).
Pulling CX riders might be something considered years down the road if the growth still continues but with the likes of chip timing becoming more popular, that may not have to happen. Lets hope everyone can ride in circles for a long time to come. They paid, they should get to suffer for the full time period.
When the officials wave the white flag saying they can no longer manage the numbers, we'll have to consider what alternatives have to be taken.
