Why I always see group cyclists on the road by I never see group runners on the road or at stadium ?

How come we don’t see many runners in the group ? Any reasons ?

That's because it's difficult for every runner to maintain the same pace and remain as one big group.

For cyclists, it's all about bravery in numbers on the roads. The drivers will be scared by the size of their 'convoy' and be less likely to hit into them.
