Training plan for the Marathon Eryri

Saturday, 24 October 2026 in Llanberis, United Kingdom. That is 2 weeks away.

When a build would have to start

ALLUNGO plans a block of a length that suits the distance, then works backwards from race day. For this one:

Too close? The next one

The organiser runs this the fourth Saturday in October, which puts the 2027 race on Saturday, 23 October 2027. That date is not announced yet, so check it before planning to it — but a Marathon build for it would start the week of 14 June 2027.

On the day

One distance: Marathon. Entries, course and timings are marathoneryri.co.uk’s. They decide when entries open and close, and whether the race runs at all — ALLUNGO sells nothing here and takes nothing from them.
