2019 Race Information

Now in its 29th year, the Cosmeston Relay Race is a hugely popular 3 mile, chip-timed, baton relay race in the picturesque Cosmeston Lakes Country Park.  It’s organised by Penarth and Dinas Runners (email:  The 2019 race will be held on Wednesday July 10th at 7:00 p.m.


Cosmeston Lakes Country Park is one of the finest country parks in South Wales and is a designated local nature reserve. It offers some scenic running, with views of the lake to start, open countryside and a shaded wooded section.


Each runner completes 1 circuit of the 3 mile (approx.) undulating course in teams of either 3 or 4 runners.  There are 11 team categories with plenty of healthy competition – and chances to win prizes for both athletic club and all-comers teams.


For the second year in succession, a record capacity field of 250 teams has entered – and the race sold out in 15 minutes.


Read on for information about the race.  A full race information pack with detailed joining instructions will be posted here in the week leading up to the race. Please contact the Race Director via email ( with any enquiries.

  • The entry fee is £24 per team of 4 (Senior Men and Masters Men 35-44) and £18 per team of three (all other teams). There is no longer a separate  card processing fee.
  • Team managers can enter a single team or multiple teams, up to maximum of three per transaction.
    • Groups or clubs who want to enter more than 3 teams will need to make multiple transactions. They can decide to appoint multiple Team Managers in advance if they wish.
    • Please only enter teams where all team members are already known.  We’ve noticed that putting in ‘blank’ teams just to reserve a place leads to ‘no shows’ on race day, effectively denying other teams the chance to register when entries open. 
  • Entries are now closed. There will be no on-the-day entries.
  • No refunds will be given for teams/runners that are unable to take part, or  if a 4-man team changes to a 3-person team category. 
  • Team changes can be made via an online self-service link that is included in the confirmation email. This facility closes at 6:00 p.m. on Monday July 8th, 2019.  After this, team member (but not team category) changes can be made off-line up until 6:30 p.m. on race day. 
  • If it’s necessary to cancel the race at short notice due to inclement weather or for another reason, then entry fees will not be refunded. If feasible, the race will be re-scheduled to a later date, with runners’ entries valid for the alternative date or transferable to other runners.

Parking, Facilities and Race HQ


  • Free car parking is available near the park entrance, directed by marshals. It’s a 400m walk from the car park to the race HQ, which is in the barbecue area of the park across the east lake from the entrance (see course map).
    • Please car share, use public transport, or come on foot if possible to minimise the road traffic associated with the race and to ease pressure on the car park space.
  • Toilets are available near the car parks and will be open until after the race.


Baton and Number Collection


  • Team Managers can collect their team batons (containing timing chips) and team race numbers on the evening of the race from the race HQ area from 5:30pm
  • Team Managers will need to attend a pre-race safety briefing at 6:45 p.m.


Footwear Choice


  • Whilst good road shoes should be o.k. for the course, it can be uneven and slippery underfoot in places when wet – so it’s recommended runners wear trail shoes if available (no spikes) for extra grip.


Fitness to Run
