They weren't at full speed. They were trying to evade other people and then trying to out do each other. Isagi only seems faster because he's hiding in their blind spots and ran forwards so they had no time to react.
@Sonaldo
He didn't move faster. He reacted faster. He figured out where the ball was going to be at a much faster rate than before and as a result, he could place himself in a better place than anyone else.
@RaijinWolf
To add to that, he didn't even win the second time. He just got onto the same level and still got dicked on. Rin is still miles ahead of him, with the only thing he's slightly better at is his mental game and that's only slightly.

Other Europeans not eating tomatoes isn't that stupid during that time. Tomatoes are actually related to nightshade, so it wasn't that crazy of an idea to think that tomatoes are poisonous. In addition, travel of information took much longer then than it does now.
