You have seen and you will continue to see these guys on the Hilly route. Always going slow, looking for trouble. But they usually don't make trouble; they fix it. Give 'em a nice wave if you don't need any help, but tap the top of your helmet if you do.

The help they can provide should not be emergency first aid nor a simple tube or tire replacement after a puncture. The former should be a call to 911, and the latter you should be able to accomplish yourself.

• SAG stands for Support and Gear.

• SAG vehicles roam the Hilly Hundred route, looking for cyclists in need of support.

• SAG vehicles are in constant contact with Hilly Headquarters by means of HAM radio.

• SAG vehicles drive in the opposite direction of bikes, so as to have the greatest coverage possible.

• If a SAG vehicle picks you up, and you need a simple item of bike repair, he will deposit you at the next rest stop in his direction of travel, which you probably have already passed. If you or your bike are beyond repair, the SAG vehicle can bring you all the way back to the Edgewood High School in Ellettsville.

• SAG vehicles will temporarily be stationed at each of the 3 rest stops each day, awaiting an assignment or their turn to patrol.

The Hilly Hundred wishes to thank the many non-biking individuals who give up most or all of their entire weekend to help us -- and you.
