TIME: 10:00am – 4:00pm

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. 

 

PRE-RACE TALK: 1:30pm and 3:00pm with Sally Drake from MSE Racing, Stephe Rebeck from Backyard Lifeguards & BYLG Sport and a USAT Official. 

RACE PACKET: 

There will be 5 specific items to be aware of -  

  1. Wristband: There will be a wristband with your race number. These must be worn to access transition on Saturday and Sunday. If you misplace this band, you will need to secure a new one prior to entering transition. 

  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  

 

HOW TO RACK YOUR BIKE: 

You will rack your bike according to your race number. Look for your number at the end of each rack. Bikes must be racked in alternating directions, preferably by the seat.

If you are currently a USAT member, please make sure to bring your proof of membership when you pick up your packet. If you do not bring this proof, you will be charged the one-day membership fee. If you are not an annual member, you will need to purchase a one-day membership (to insure you as a triathlete) before you are able to pick up your packet. One-day membership will be collected when you register online.

ADDITIONAL RELAY INFORMATION:
Relay triathlon is a WONDERFUL way to experience a triathlon if you are not ready to run the whole thing, if you are not capable of competing in a specific leg, or if you just want an opportunity to share something unique with friends or family. A triathlon relay can be done with 2 or 3 people. The team can consist of all male participants, all female or mixed. Each person does 1 or 2 legs of the race. The timing chip will have a Velcro strap on it and is handed off from one athlete to the next in transition. All athletes receive full swag and finisher medals.


SPECTATOR INFORMATION:
Spectators, the unsung hero of the triathlon. Without family and friends there to cheer us forward, the rigors of our sport would be far more difficult. MSE Racing is dedicated to ensuring that these vital portions of our triathlon family are given the opportunity to enjoy themselves while they wait for the next opportunity to see you fly by.


MSE Racing is proud to provide the following amenities:

  • Sign making craft table for kids

  • Yard game section
