The «Lon Las Cym­ru ultra» is a 250 mile non-stop race from Holy­head to Cardiff Bay down the cen­tre of Wales cross­ing sev­er­al moun­tain ranges. It‘s pos­si­bly the longest non-stop road ultra in the UK. This film is the sto­ry about Gor­don Hugh­es and Vic Owens as they attempt to run this race in under 88 hours in Octo­ber 2021. It is, as one of the com­ments said, a momu­men­tal jour­ney by some mon­u­men­tal people.
