Another one in the book! And what a nice sunny day for a run! 126th Boston Marathon (my 4th Boston but 90+ marathon overall). And thanks #hilton for the flexibility on the late checkout! I made it back with time to shower —how great did that feel?!?! Right before I hit the train back to NYC (I’m sure everyone else on the train would send their thanks too 😂) #boston #bostonmarathon #gatoradeendurance #enduralliance #marathon #endurance #enduranceathlete #runcoach #triathloncoach #empiretri #newengland #goodr #goodrsunglasses #hilton #latecheckout #notstinky (at Boston, Massachusetts) https://www.instagram.com/p/CcgSclMOqbo/?igshid=NGJjMDIxMWI=
