I ran the Charles River Link Trail Westbound. I could not find any previous entries on this trail. The Charles River Link is a 16-mile regional trail along one of the most scenic parts of the Charles and that will eventually provide a connection between the Bay Circuit Trail in Medfield and downtown Boston.
Finally got around to making an account! I attempted this a little while back on a humid day. Took the Green Line out to Woodland, then took a Lyft down to the southern terminus (was about $20 if I remember correctly, the driver was extremely confused). Got lost as there's an unmarked turn (that goes down somebody's driveway!), if you do attempt, make sure to read the full description online! There was also some constructions/trail re-routing near the end, so watch out for that as well. Ended up bailing because of the bonus miles, but I plan on getting back out there at some point soon! A very worthy trail that would support some speedy times for the right person!
