11 February | 10:00 AM | Sunday – see you in 2024!
The Super Sunday 5 is the big event in Kendal Square!
The 5 Miler and 5K drew about 2,000 runners in 2022 and should be even better in 2023!
I’ve run the 5K in freezing cold and I ran the 5 Miler in above freezing temps. You never know what you will get, but you will have a good time.
This well-organized running event features hot food and a huge beer garden. They always have a dozen or so local breweries on hand to get the party rolling and keep it going into the early afternoon.
* April | 9:00 AM | Sunday – see you in 2024!
2023 was the 35th running of this race. It’s great to see a race that has endured through the years and survived COVID-19.
Managed by Friends of Cambridge Athletics, this race loops the Fresh Pond Reservation. It stays on the trail and the service road inside of the reservation.
I ran this race when it was a 5 mile race in 2015. My recap from 2015.
Fees benefit CRLS student-athlete scholarships, team travel/equipment, and The Andrea Harvey Memorial Fund to help victims of domestic violence.
Parking is available at the Tobin School, 197 Vassal Lane. NO parking at Fresh Pond, and they will ticket!
2023 registration was: $35 for adults and $25 for students. Race day registration will be $45 for adults and $35 for students. CRLS students 18 and under can register for FREE.
Fee for walkers was $35.00

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.
2023 registration was $43. Get the Season Pass for $140, run all four races and get a cool 1/4 zip fleece!

This may have been a “one and done” as I have not seen any information for the 2023 race.
