Cardiff Half Marathon

Each year, event organisers Run 4 Wales (R4W) donate 100 free places in the race to people who can use them as a vehicle to improve their health and wellbeing and support them through their journey to the start line, often working with groups and communities typically excluded from running or who face barriers to entry.


Those selected to join will receive:

  • A free entry into the sold out Oysho Cardiff Half Marathon
  • A free 100 Club technical t-shirt, to wear whilst training and on event day
  • Access to a closed social media support group, to engage with others taking part, ask for advice or share progress
  • An invite to a pre-race training event, including a talk with a running expert – an opportunity to ask questions and participate in a guided training run
  • A VIP start line experience on race day, including access to an exclusive Cardiff Castle start wave
  • A free one-month trial with run coaching app Coopah, which offers instant personalised and adaptable training plans, access to coaches and more
