The Mighty Squirrel Ride


Have you been looking for a long, hard/hilly ride that leaves early on a weekend morning and gets you home by lunch? The Mighty Squirrel is for you. This metric century takes you from Waltham out to the Harvard hills and back and is targeted at experienced riders who can maintain an average pace of 16/17, or 19/20 mph (pending n the group size w can have a third group).

This is a no-drop ride and we’ll go as a group, breaking into packs of 10 – 12 riders depending on the number of people who show up. Navigation is via GPS.

We suggest you bring your favorite gels, bars, drinks for the ride as we won’t have a designated lunch stop; just in case, there will be a short rest stop at the Harvard General Store where you can use restooms, re-stock and refill your water bottles.

Please plan on joining us at the Mighty Squirrel Brewery for a cold one upon return.

The ride will depart promptly at 7:30 a.m. Please plan to be there 10-15 minitues prior.

Please check for weather cancelations day prior to the ride by 8PM.
