Cambridge 5K Race Directory
Updated December 28th
The Cambridge 5K Race Directory 2022 has morphed into the 2023 Cambridge 5K Race Directory.
2022 saw the return of in-person Cambridge 5K events, and race directors tell me that registrations are picking up.
We’re not back to normal yet and we lost a few races over the past two years but we are headed in the right direction, just as runners always do.

The Super Sunday 5 is back 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 – no official date for 2023 yet
2022 was the 34th running of this race. Managed by Friends of Cambridge Athletics, this race loops the Fresh Pond Reservation.
I ran this race when it was a 5 mile race in 2015. My recap from 2015.
