I'll call him RR (his actual initials) to disguise his name.
RR came out for track his senior season. He had played basketball in the past and been stellar but had been kicked out for grades. He got his grades up and dicked around at practice all season... coaches kept him around because he was so good.
By the end of the season he had run 1:54 in the open 800 with no base and probably 2/3 of the practices of a normal athlete. He would skip practice and go hit around with the tennis team, where he easily could have been varsity too. He dominated every local invitational. At state he could have won but got 5th because he went out like an idiot and got eaten up by a pack of 4 runners who drafted off him.
His most impressive display though, was the 4x800 at state that year. Our 4x800 had 3 incredible legs and one really mediocre one. They put the slowest leg second and he ran a 2:08, which had us in 15th (2nd to last place). Then RR got the stick. He passed TWELVE teams, running 1:56.0 on a cold and windy day, setting the team up for their third place finish.
Got a track scholarship, dropped out, and started his own dance studio (he was also an incredible dancer). I watched this guy in awe. I saw guys run faster (we had a guy hit 1:51.9 on a relay split when I was a junior), but I never saw anyone who was so fast with so little effort.
