Best running app for iPhone 4

[Huffle]

Hi, not sure if I’m posting this in the right place but is there an app that will track how far you’ve run (more of a fast waddle if I’m honest) I don’t want to count steps, just see how far I’ve gone. All the apps I’ve tried to download say they need ios10 and I don’t think I can get that on an iPhone 4s?

I still have my iPhone 4 so I will have a look. You're right though, not a lot will work on my old phone. I love it though.
