The CF64 Winter Race

2020 Race Results are now on-line



  • The CF64 Winter Race is a 6.4 mile (10.2 km) mixed-terrain race set off-road entirely within the picturesque Cosmeston Lakes Country Park in Penarth.  The race is organised by Penarth and Dinas Runners (email: and licensed by Welsh Athletics (Licence No. SOUTH R.A.C. TR-05)
  • 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 lakes, open countryside, marshy areas and a shaded wooded section.
  • In establishing ‘CF64’ in 2018, the aim was to put on a low cost, ‘no frills’, mid-winter off-road race for the local running community.  The course will challenge experienced runners, particularly those looking to sharpen their mid-season cross-country speed, but is also suited to newer runners looking to try out an off-road mixed-terrain race.  There’s trails, mud, woodlands, more mud, hills, fast tarmac sections and some great scenery to enjoy on the twisting course around the park.  Plus the usual excellent level of race organisation and support from Penarth and Dinas Runners and friends.

Course Information

  • The undulating course is entirely off-road within the park, on a variety of surfaces, through woodland and meadows, scrubland, and a few marshy areas (see course map and description below).
  • The course is marshalled at all key points, with additional signage to guide runners through unattended sections.  The course route, directions and main marshal locations are indicated on the course map.  Mile markers will be positioned around the course.

Course Description

  • Starting at the barbecue area, most of mile 1 is run on wide, undulating trail paths around the Western Conservation Lake, finishing with a short grassy climb after entering the Dovecot Field area of the park.
  • Mile 2 initially follows the top edge of open fields, then drops down to the bottom corner of the fields, where it’s likely to be wet and muddy.  The course then runs alongside Sully Brook, doubling back through two gates heading into mile 3.
  • A short grassy climb early in mile 3 leads back to the trail paths and, after 3 left turns in quick succession, down into Cogan Wood.  This should be a fast section of the course on wide trail paths.  Runners emerge from the Wood up a short gentle incline turning right into the open land of the West Paddock.
  • Mile 4 starts just before the Dragonfly Pond, located on the runners’ left, after which the course heads round into the lower main part of the West Paddock.  The initial open meadow turns wet and marshy, with areas of reeds, leading out of the West Paddock.  A kissing gate (single file, please) leads onto a short section of tarmac path on Mile Road before a left turn into the East Paddock via a short, steep, stony descent.  Marshals will direct runners to take care on this section.
  • Runners will turn for home just after the 4 mile markers at the start of mile 5.  The open land and meadows of the East Paddock are likely to be wet and muddy, before the second kissing gate (single file again, please) leads back onto the Mile Road and then a second pass around the top of the Western Conservation Lake and back into the open field area.  A grassy downhill section leads into mile 6.
  • The course again loops either side of Sully Brook, before a final sharp grassy hill leads from the side of the Brook up to the top of Dovecot Field and the start of the run for home.  The 6 mile markers come up as runners exit the Dovecot Field and re-join Mile Road for the final time in a gentle 0.4 mile uphill run, mainly on tarmac, to the finish.  Just after the bridge between the 2 lakes, it’s a final right turn and then a 150 yard sprint down the finish funnel to the line.
