Team Relays and Solo Challenges

The Trail Festival's newest relay is Here! The ERS has decided to adjust what the SMR relay looks like, by switching it from a 3 person 50K relay to a 2 Person Marathon relay, in which both team members will each have to run the Half Marathon course. Here is the breakdown:

Teams of 2 ANY Combination... all female, all male, or Co-ed.
Each member of the team will run the Half Marathon course individually.
One bib will be assigned to each team.
Teams will swap out bibs at the dedicated checkpoint near the finish line.
ERS will supply bib belts to each team to for easier bib swap.
First team member will begin the race with the solo Half Marathon runners at the start line.
Second team member will begin at the dedicated checkpoint, BUT finish under the finish line arch.
The TOTAL time for the team will be recorded as the final result.
Top 3 overall teams will be awarded.

REGISTRATION:

On the event registration site, you will find Marathon relay Team Captain and Team Member registration. To make it an easy process during registration, Team Captain's will be responsible for race fee and the creation of team name. Team Members will use the TEAM MEMBER option to register themselves and select the team to join. All team members MUST register through the registration platform.

Runners who sign up for either challenge will have the difficult task of completing multiple events in a single day. Do this and win our Moosehead Challenge or Baby Moose Challenge Medals.

Moosehead Challenge- Complete the Half Marathon, 10K, and 5K
- Total time to complete: 5.5 hours
- Total Miles: 21.4 Miles
- Runners will be given 3 bibs, which they will need to use during the challenge. Every distance means a new bib.
- Use the allotted time as you will. Meaning finish a race and rest for a few minutes, or finish 1 race and head immediately back out
- Runners will have to begin each race and cross the at the start line every time.
- Runners must cross the finish line mat after every distance.

Please note:

Your times will be calculated for each race. Your race time begins when you cross the start line. This allows runners to still podium in each of race categories. Podium results will be adjusted accordingly to include challenge runners.
We will have a bag drop area that runners can store bags. This bag drop also serves as the checkpoint for the 50K runners.
