Right now I use a pair of running shorts with a zip pocket middle-rear, just below the waist band. These are really tight shorts so I wear baggier running sohrts over the top - don't want any ladies fainting as i sprint past!
This is comfy. But said shorts are at the end of their life and I haven't found anything similar to replace them.
How do you carry your iphone? I like using it for strava, rather than music, so I don't need constant access and I don't want one of those straps that goes on your upper arm.
One of my mates runs a league in my town, for U8's and U9's. He's been threatened on more than one occasion, broken up fights between parents, covered boy's eyes and ears because of the foul language being shouted by grown-ups. These people seriously think their boys are going to be star players when they fail their GCSE's.
