Where can I park for the race?

There is a large parking field at the end of Jack Rabbit Lane, off Route 33, next to Stratham Hill Park. Police and volunteers will direct you there. You can also park along Route 33 in front of the Park. Please arrive early so you’ll have plenty of time to park, pick up your packet, use the port-a-potties (yes, there will be lines!), and cross the street to the race start. In fairness to those who arrive on time, we will not delay the start for late-arriving racers.

Can I park near the finish area?

There will be NO RACE PARKING at the Great Bay Discovery Center. (If you do manage to get in to the Center parking lot, you will not be able to leave until every racer has finished and the timing mats have been pulled up.) You can park on nearby side streets, and can then do your warm up run up Depot Road to get to the starting line (approx. ¾ of a mile).

What is the MacKenzie Mile?

This is a unique race within the 5K. The first male/female racers to reach the one mile mark will each win a $50 prize (assuming they complete the race at close to the same pace).

Can I change or add a Team name?

Of course! Please email the Race Director at gb5k@greatbaystewards.org and let us know the team name that you’d like to add or join. Remember, deadline for Team shirts is October 1, 2021.

How can I get back to my car after the race?

There will be a shuttle bus from near the finish area to Jack Rabbit Lane. You can also walk up Depot Road back to the parking area. It is about a one mile walk, and a good post-race cool-down.

If you have a question that we didn’t answer, please contact the race director.
