The 2014 Boston Marathon took place today, and on Twitter, many runners, supporters, and spectators kept track. Last week, the #BostonStrong hashtag marked the anniversary of the bombings, and today, that same spirit endures.

The #BostonMarathon hashtag offered some unique insight into the world of marathon running: Endurance, stamina, and mental willpower all factor in, which makes this year’s marathon, and the stories of survival, even more poignant. Last week, bombing survivor Marc Fucarile was married at Fenway Park. This year's marathon also marks the last for inspirational father-son duo Team Hoyt

Today, Meb Keflezighi became the first American to win the marathon in 31 years. Rita Jeptoo won the women’s race.
