Meet the fastest guy you've probably never heard of

BBC Sport Wales catches up with Sam Gordon - the fastest man you've probably never heard of.

Gordon, 24, is the fastest Welshman currently competing and is aiming to be the first Welsh athlete to run 100m in under 10 seconds.

But because he isn't fully-funded, he also coaches sport in local schools. Something, he says, makes reaching the top of his sport even harder.
