We encourage athletes to pick up your packet today and drop off your bike today instead of race day! You can leave your bike in transition; we will have security all night to keep it safe. Leave your gear at home, that comes with you race morning. 

 

You CANNOT pick up someone else’s packet unless you are doing a relay. Make sure you bring your Photo ID and bike.

  2. Timing Chip: You will receive your timing chip when you pick up your packet at the expo on Saturday. DO NOT FORGET THIS ON RACE MORNING. You will wear the timing chip on your left ankle with the chip portion facing out. This is how you will be timed. NO CHIP = NO TIME = NO RESULTS.  

  3. Bike Sticker: place this on your bike, usually the seat post is the best place or the top tube.  

  4. Helmet Sticker: place this on the front of your helmet.  

  5. Race Bib: You are only required to wear your bib while you are on the run. It should always be forward-facing and visible. You can affix it to you using safety pins or a bib belt
