The Boston marathon is THE marathon. I received my bib just 2.5 months before the race and the entire experience was a whirlwind from start to finish. The course is HARD, with elevation gains in miles 16-21. The downhill start fools you and makes you think you’re feeling good, but comes back to hit you in the later miles. The crowd support at Boston is unmatched, and I would love to return one day!
