NEWBURYPORT — More than 1,200 cross-country runners from 32 Massachusetts and New Hampshire high schools converged on Maudslay State Park Saturday morning to help out the Newburyport cross-country team in the 13th annual Clipper Relays.“It’s interesting,” said Newburyport cross-country coach and Relays mastermind Don Hennigar, whose program benefits from the entrance fees, “because you don’t really knows how the other teams put their teams together. Some of them put their best three guys together. Some will split them up, but you still get a little bit of an idea of what is going on. You can see who has strong teams and who might not.”
