The Pen Llyn Ultra 100 Mile Race



With 3 Mount Snowdon’s worth of ascent (11,085ft / 3378m) a cheeky 2.68miles of constant uphill from mile 7 are just a few of the “Distractions” in store for the Pen Llyn Ultra 100 competitors.

You have 29 hours to complete. so please do not sign up and embarrass yourself unless you know hand on heart you can complete it.

Starting at the same place at midnight you will be setting off in the opposite direction, running along the beach over to the headland at Hafan Y Mor then across and up Lon Coed and round towards Clynnog Fawr in the shadows of Gyrn Coch.

As you approach the village of Trefor you will now have in your sites the Quarry where you will run up and be faced with the majestic brickwork of the old quarry. This is also the location of your first Honesty book & water (It’s in one of the ruins of the miner’s hut and also where Sean Conway spent the night on his cycle around the UK).

Descending the track towards Lithfean then following the road to the first checkpoint at Huw’s Farm. That’s right no checkpoints till then, over a marathon distance without supplied food (Good Practice for Spine). We did warn you. Your first CP though is in a farmhouse. warm drinks & food aplenty.

Fed and watered you now head to chase down the other competitors along the coastal path to Llanbedrog (The very steep climb up Llanbedrog headland to The Tin Man sees the location of Honesty book 2) then along on the beach to Abersoch towards toward CP2 then down and around the headland past the wild horses of Cilan and onto the beach at Hells Mouth.

Most probably the cows will have been milked and are now grazing in the fields you have to pass, so please be vigilant. On the main road, you will arrive at CP3 in the Car park Near Rhiw, then across some really scenic woodland to another steep climb.Following around the coastal path and into the very picturesque village of Aberdaron (This is also where CP4 is) You will now have your biggest off-road stint of the 24hours.

This side of the course of Pen Llyn really does knit its way into every crook and cranny, spectacular views of Enlli will not really help.It will feel like forever before you get to Porth Colmon and CP5 then head down to TY Coch and CP6. You will most probably be now running in darkness so please be extra vigilant of the cliff edges.

Running through Nefyn and along the path to Nant Gwrtheyrn, you will have a 25% Ascent before reaching CP7 then down the path and road you ran in the morning and out towards the Ultra Village in Aberech Sands and onto the beach for the run into the finish.

Good Luck. You will need it.
