Does anybody know: Manufactures of Track and Sports Minatures

Has anybody ever found?

I ask on behalf of, ahem, a friend (nay I cannot deny it is a blood relation, an older brother), who despite a brief dally and foray with ACW miniatures several years back, he remains a board gamer rather than historical miniatures wargamer, with a very heavy sporting bias.

His simple request was for manufactures suitable for Athletics games (20mm, 25mm, 40mm or even 54mm size), namely track sprint races (100m, 200m and 400m). I have tried searching but I have failed dismally. Can anyone help?
