Hosted at Officer Candidates School aboard the Marine Corps Base, the Quantico Tri is sure to bring fast times and fun to all who participate. Located on the famed training grounds for all future Marine officers, this event is set to feature an open water swim in the Potomac River, followed by a swift 12.4 mile ride. Once athletes are finished with the bike course, they will run a scenic 5K which offers a 3.1 mile run through Quantico history.

Transition Area
After parking on the parade deck for the event, please access the transition area by walking over the bridge. Triathletes may enter the transition area beginning at 5:30 a.m. on event morning. All bikes must be racked by 6:45 a.m. before the start of the first swim wave. Bike racks are numbered and triathletes must put their bicycles and gear in their designated bicycle location. Each bike rack can hold six bikes. As such, each athlete’s space is approximately 3 feet wide by 3 feet long. Once a bike is in place, the remaining space is approximately the same size as a standard bath towel.

1. Bike storage will NOT be provided the night before the event.
2. Glass containers are NOT allowed in the transition area.
3. Only triathletes and transition workers are allowed in the transition area. Please advise family and friends to remain outside of the transition area.
4. Transition area times are included in the final results.
5. Rack bikes on race morning on the rack that corresponds to assigned bib number.
6. Participants will NOT be allowed to mount their bikes in the transition area and will be required to dismount at the designated spot outside the transition area.
7. Triathletes must show their race number to remove their bicycle and gear from the transition area after the race.

Event Progression
1. Swim - When triathletes finish the Potomac River swim portion of the event, they will enter the transition area and proceed to their designated bicycle rack. Each triathlete’s swim time will end when they cross the timing mat located near the swim exit.

Team River Runner is providing volunteer kayakers to observe the swim course. Founded in 2004 at Walter Reed National Military Medical Center, Team River Runners wounded and disabled war veterans and their families the opportunity to participate in adaptive paddling programs by offering paddling sessions in 45 locations across the nation. 

2. Bike - Bikes may NOT be ridden in the transition area. It is important to use extreme caution when departing the transition area, it may be very congested! All athletes must put on their helmet and snap the strap before mounting their bike. The helmet must remain on and buckled until the triathlete dismounts and racks their bike. Not following the helmet rules may result in a disqualification (DQ). Bike times will start when triathletes depart the transition area through the 'Bike Out' chute and end when they re-enter the transition area through the 'Bike In' chute. Once the bike portion is completed, triathletes will return their bike to their designated spot in the transition area.

3. Run - Triathletes depart the transition area by exiting through the 'Run Out' chute. Triathletes run time will begin when they depart the transition area at 'Run Out' and end when they cross the finish line.

Bib Packets
The helmet number is the small sticker on the front of the bib packet. Peel the sticker off of its protective paper and place it on the front of helmet. Placing the number on the side of the helmet will make it harder for the officials, photographers, volunteers and event staff to identify participants. The bike number is the largest piece of paper and is located in the back of the bib packet. The number is upside down at one end and right side up at the other. When folded over the top tube of the bike, the bib number can be read easily from either side. There are two adhesive strips on the backside of the bike number. Peel the protective paper off the adhesive strips and then place the number on the top tube of the bike. The run number is the middle sized paper in the bib packet. Wear this number on the run course. This number MUST be on the front of the participant. Not having the run number on the front may result in a time penalty. Safety pins will be provided at Packet Pick-up.

Tattoos will be distributed at Packet Pickup on Friday, August 21. Participant number tattoos should be applied on both arms and one age number tattoo should be applied on the back of the leg of one calf muscle. Check out this video to learn how to properly place your tattoos.

Corn ChipFinish line hospitality features CORN THINS.  Delicious, and show healthy snacking can be easy...even for fussy eaters. Don't confuse them with rice cakes, as CORN THINS are made primarily from corn, so taste great - like popcorn squished into a cripsbread. CORN THINS are gluten and GMO free, have low levels of fat and good levels of fiber, so not only taste delicious, but are super healthy, so are perfect to be eaten by the whole family
