I'd appreciate it if anyone could help me with this. In a competition, or a race, if the first one/team stands the first position with a great distance, then how can we describe it? Any idiom, expression or informal term, please?
How about 'to run rings round others'?
And, any adjective, to describe such a person or team, please?
How about clear winner?
