AUGUST 26, 2023




Teams consisting of 3 or 6 members will travel the route from start to finish with each team member running 3 legs (6-member team) or 6 legs (3-member ultra team).

Teams will start in waves between 4:00 am – 8:30 am; slower teams earlier and faster teams later. Team start times will be announced several weeks before the event so you can plan your accommodations and travel.

The course is split into 18 relay legs with an exchange zone between each one. Race Start, Leg 1, Exchange 1, Leg 2, Exchange 2, Leg 3, Exchange 3, etc.


  • Due to ongoing construction on Canal Street in Blackstone, Massachusetts – Exchange #2 has shifted to Blackstone Town Hall – this change has also adjusted Legs #2 & #3

Team Pace Calculator

An easy-to-use Pace Calculator has been set up in Excel for team captains to download and determine team overall pace. Race start times are determined by team pace. If you find that your team’s pace has changed, please log into your Haku participant account and make the change by July 9, 2023 to update it.

Please note: calculator does not work on iPhone or iPad.

Six Member Team

  • It is STRONGLY RECOMMENDED that all teams use ONE vehicle
    • TWO VEHICLE TEAM GUIDELINES: To reduce vehicle congestion and traffic, teams are only allowed to have ONE vehicle at a time at each exchange, with the exception of Exchange 6 (Putnam), Exchange 12 (Willimantic) and the Finish (Hartford). Only the vehicle with the team member running the next leg is allowed to park at the exchange, no exceptions. Teams electing to use two vehicles must first drop off and retrieve their team members, and then make any team member and/or vehicle switches at an alternative, off-course location, away from the exchange area. Recommended off-course exchange location areas will be provided for all minor exchanges (Exchanges 3, 9, 15). See respective relay maps for details.
  • Six member teams will exchange at every exchange location:
    • Runner One will complete legs 1, 7, 13
    • Runner Two will complete legs 2, 8, 14
    • Runner Three will complete legs 3, 9, 15
    • Runner Four will complete legs 4, 10, 16
    • Runner Five will complete legs 5, 11, 17
    • Runner Six will complete legs 6, 12, 18
  • One member of the team will always be running, while the other team members drive to the next exchange location. At each exchange, relay teams must check in with the volunteer on location before passing the “baton” to the next relay team member.

Three Member Team

  • Three member teams travel in one vehicle.
  • Two Options for Three Member Teams:
    • OPTION 1: Exchange at every exchange location
      • Runner One will complete legs 1, 4, 7, 10, 13, 16
      • Runner Two will complete legs 2, 5, 8, 11, 14, 17
      • Runner Three will complete legs 3, 6, 9, 12, 15, 18
    • OPTION 2: Exchange at every other exchange location
      • Runner One will complete legs 1&2, 7&8, 13&14
      • Runner Two will complete legs 3&4, 9&10, 15&16
      • Runner Three will complete legs 5&6, 11&12, 17&18
  • One member of the team will always be running, while the other team members drive each other to the next exchange location. At each exchange, relay teams must check in with the volunteer on location before passing the “baton” to the next relay team member.

There are 17 exchange zones along the course. All of them will include water and portalets. Two major exchange locations have been established to assist teams with refueling and resetting themselves during the race. These two locations will also offer refreshments, entertainment, medical aid and other extra services.

1st Major Exchange (Exchange Zone #6)

    • Rotary Park, Putnam, Connecticut

2nd Major Exchange (Exchange Zone #12)

    • Jillson Square, Willimantic, Connecticut


Teams are required to maintain the same sequence and rotation of runners throughout the race (see table above for runner rotation breakdown).
When determining your team’s order, Captains should consider the following: leg distance, course terrain, time of day, and runner fitness.


If a runner is unable to continue in the event due to injury or illness, the following team members must finish the event with the remaining runners continuing in the same sequence.

Teams must begin the event with six team members if they are in the 6-Person Team division, and 3 team members if they are in the 3-Person Team division. No exceptions.

Teams are required to maintain an average pace of at least 10:30 minutes per mile to complete the event within the 16.5 hour time limit. We understand that teams may consist of runners with varying abilities, so periodic checks will be done to make sure your team can complete the race before the finish line closes at 8:30 pm. It is crucial to accurately estimate your team pace to assign your start wave. More…

Use the Pace Calculator to help figure out your team’s average pace.


Due to the extensive timeframe and complex nature of the event, completion is required within 16.5 hours to ensure support services and safety. Any team that has fallen behind the 10:30 minutes per mile average pace or experiences unforeseen circumstances by the time they reach the 2nd Major Exchange Zone (Exchange Zone #12) – Jillson Square, Willimantic, Connecticut, will have the following 2 options:

  1. End their run and proceed directly to the post-race party in Hartford, OR
  2. “Skip Ahead” to a further exchange location and continue the run.

NOTE: Teams that do not run all legs will still be included in the finish results through the time of the last reading of their timing chip (no finish time will be provided).
