Meb Keflezighi, who had the best chance of ending a three-decade domestic drought at the Boston Marathon, withdrew from the 117th running on Friday because a nagging calf injury had cost him too much training time.
“I’m very disappointed,” said the 37-year-old Olympic medalist who would have been making his third attempt in eight years on the Hopkinton-to-Copley Square course. “My training was going well in January and February, which had me very excited about the possibilities this spring. I even skipped the New York City half marathon [March 17] to focus on getting healthy for Boston but unfortunately it wasn’t enough. I ran out of time to recover enough to compete for a victory.”
