The Super Sunday 5 has moved to Mighty Squirrel in Waltham!
2024 registration was: $40 for adults 5K or 5 Miler, $17 for 18 and under for 5K or 5 Miler. Or come for the party for $20!
Proceeds from the 2024 event will go to support the families of Officer Paul Tracey and National Grid worker Roderick Jackson, tragically killed on Dec. 6, 2023.
This year the apre party will be in a giant (20,000+ sq. ft.) beer garden with live music from Beach Nights, Karate Show, and DJ Dukes. The three largest teams also get special perks.
The 10 largest teams (by January 31st) will get a team tent in the beer garden. The two largest teams will have access to party buses.
There will also be indoor bag check and changing areas. This will be awesome!
Parking is available and you need to buy a parking pass ahead of time for $3.00. So essentially it is free!
While I will miss the Kendal Square location, it will be fun to run in Waltham on a new course.

This race takes place off of Mass Ave on Sidney Street.
This is a large race with a great post race party. Public transportation is a good idea, keys and kids are optional.
I’ve run this race several times and it is always a good time. It’s great to see the fast runners and hang out with friends, old and new, at the apre race party.
This is a flat course and over a mile of the race is down Mass Ave. Total elevation gain for this Cambridge 5K is 30 feet. Get 19 of your friends to form a team and get a VIP tent complete with cold beer. The tent comes with a table and they are close to the music and pouring stations. Plus they make a great place to stow your gear and hang out with your friends.
2024 registration is open $40 for The Spring Classic or get the Season Pass for $155, prices increase February 20th.
