1) Tanni Grey-Thompson (11 gold medals over 5 paralympic games, over 30 world records, winner of the London marathon 6 times and she is British)
The others are nowhere near as great but I went for
2) Lance Armstrong (beating cancer gets him in, great role model)
3) Daley Thompson (great ambassador for British athletics)
4) Pele (advertised pills that help you get a hard on!)
5) Jessie Owens (his achievements have since been bettered by the likes of Carl Lewis, but his came along at historically the right time)
I justify the loose wiring part by the years of dedication each put into the respective sports!
