Thinking of crossing the bridge towards Kenmore Square then hugging Storrow Drive somewhere…thoughts?
Do they have a proton accelerator over there?
I did all my runs along the Charles.
According to this: http://bostonrunner.com/charles.htm Science museum to Arsenal Bridge loop is 12.6 miles
charles river path along the river for 6 miles towards Watertown, hang a u turn.
Take the Smoots bridge across the Charles. Take Beacon St. out of Kenmore towards Brookline. Left on St. Mary’s St over the bridge. Bottom of the bridge take a right onto the Riverway path. Run this for miles, past Jamaica Pond. Do loops of the pond or keep following the Riverway and run another mile out to the Arnold Arboretum where there are some good trails.
