Shaun and Shamus Evans have once again proven there is no challenge too big for them. The father-son tandem from Galway ran the Boston Marathon Monday in two hours, 55 minutes and 35 seconds.

They first gained notoriety for running across the country — Seattle to New York City — while spreading a message of inclusion.

Shamus, who was born with cerebral palsy, took in all 26.2 miles from a specialized running chair pushed by his dad, Shaun.

Shaun is no stranger to the Boston Marathon, running it six times before.
