Hello! I'm a complete running novice and until now (week 5) have been jogging along in a sporty tshirt and tracksuit bottom with a fleecy jacket that I put my house keys / phone etc in. Now that its getting warmer I am wondering how I will carry these types of 'essential' items when I no longer want to wear a jacket? Can anyone reccomend what works best... I've considered a bum bag type thing but wondered if it might be distracting to have it bumping about?
