DES MOINES, Iowa (AP) — For Calvin Smith II, sharing the same name and being the son of Calvin Smith means carrying a lot of weight. It’s not easy following in the footsteps of a former world-record holder, world champion, Olympic medalist and Hall of Famer. That’s why, at an early age, the son decided he wasn’t going to be a 100-meter sprinter like his father, but rather would make a name for himself in his own event, the 400, and stand out on his own merits.

One thing’s for sure: He certainly inherited his dad’s speed as he competes this week at the U.S. championships, hoping to earn a spot on the world team headed to Moscow in August.
