But, there are rules. At the Olympics, a Track and Field competitor is required to stay in their running lane on certain races. You step out of your lane, and bump someone, you are disqualified. I've seen Olympics Medals lost because of that rule.
Track & field rules apply to both laned and unlaned races. A runner who obstructs so as to impede another's progress and gain a material advantage will be disqualified. Bicycle races have similar rules. Looks like horse racing also has similar rules.
