I have agreed to support a friend in running in a charity 10k in May, and am a complete beginner! We are starting couch to 5k and are going to get involved in parkruns - but shamefully I don't even have a pair of trainers! I don't want to spend a fortune but would like some advice from anyone who runs on what essentials I might need that I haven't thought of. I am hoping to keep it up after the 10k so happy to get things that have some longevity too. Thanks in advance for any advice!
