Cornish Imerys Marathon and Half Marathon

IMPORTANT ANNOUNCEMENT: Cancellation of Imerys Trail Marathon and Half Marathon 2024

We're sad to announce that 2023 was the last running of the Imerys Trail Marathon and Half Marathon.

We are actively seeking an alternative race in the area for 2024 and will announce when this has been finalised.

We have been in contact with runners who had deferred entries for the 2024 race.

We'd like to thank all runners, Imerys, Cornwall College and St. Austell Running Club for all their support with the Imerys races over the years.

Spectator Information

Places where the public are able to have access to see marathon runners are:-

  • About mile 6 – Hensbarrow – where the tall mast is near Roche, park in the small car park (limited parking) at the top of hill – if you are coming from Stenalees, turn left just as you come into Roche and take the Whitemoor road, then almost immediately turn left again and follow the winding road up to the top. Runners will be crossing here into Littlejohns Clayworks at roughly mile 6.

  • If you go to Lanjeth, at the top of Hornick Hill, park in the Blackpool trail car park – walk into the trail and you will be able to see the marathon runners at about miles 11 and 12 – they will be running around the bottom of the tip inside the fence. Allow a bit of time as you will need to walk in a fair way until you can see the path over the wire fence.

  • Park at Whitemoor, the school park maybe open and then head towards the entrance to Dorothy Pit where there is a water station. There is a permissive path that you can access just inside the gate – you will see the runners between miles 15 and 16 here. You will need to view from the permissive path as the public will not be allowed to stand in the area where the water station is. You will have an excellent view from here though.

  • You can also see them by accessing the entrance to the permissive path that is opposite Allens Tyres in Whitemoor, the marathon runners will be passing through here between mile 16 and 17.
