We've teamed up with New Balance to encourage runners of all ages and abilities to celebrate their achievements.
Whether you've just smashed your 10k PB, completed your first ever triathlon or simply managed to squeeze a 20-minute circuit into your lunch break, post your messages on Twitter or Instagram using the hashtags #RWxNB and #Iamthecompetition and every week we'll pick the most inspiring posts. Check out the post below and get inspired!
Winners will receive a pair of New Balance trainers or a New Balance T-shirt. Terms and conditions apply.
