The only one that's remotely scalable is #135 even though you'll a) lose the runner really quick and b) he looks tired. The runner in #89 better defines "hustle", but his movement would likely ruin the flow if he was positioned on #135. Also, putting a runner on there sends a message immediately about who your intended audience is. If it was just a typeface that insinuated effort/movement, that might be better than trying to put clipart in there that could throw people off about the purpose of your service, which isn't just funneled to runners.. particularly with the success of technologies already devoted to them like Nike+.
