If you are going to Snelling RR please read the following from race promoter Robert Liebold.
SNELLING HAS CHIP TIMING/PLACING
Snelling road race will have chip timing/results this year as an experiment. This means there will be two steps to registration. (1) You will need to get in line for registration as usual (show license, sign/turn in form, pick up numbers), and then (2)go to the chip desk, to pick up your timing chip. There will be people there to help put them on your bike, so bring your bike to that line.
Immediately following finishing (or dropping out), go to the station just off the loop before returning to Snelling town to have your chip removed. Do not cross the finish line backwards after finishing; it will give you a later finish.
