One Fly 2018
One Fly 2016


The One Fly Festival is a celebration of everything that is great about fly fishing with two days that mark the opening of a new season on the chalkstreams in late April. Do join us for the Fly Fishing Film Tour, the Iron Man Fly Tying Challenge and the River Test One Fly.

Lee Cooper
Lee Cooper – 2016 Champion


In association with Orvis this competition challenges all-comers to create the perfect fly within 15 minutes, but with a twist. The contestants are given no prior knowledge of the fly-tying materials. At the sound of the bell each is given an identical bag of fur, feathers, dubbing, flashy materials and hooks. What and how they tie is up to them, the outcome only limited by their skill, imagination and the ticking down of the clock. Just to spice up the challenge even more, a mystery material is given to each contestant half way through the first round. This must be included somewhere in the finished fly! When time is up luminaries from the fly tying industry will judge the flies, eliminating all but three of the contestants who go forward to compete in a winner-takes-all tie-off the same evening.

Come along and enjoy the spectacle - entry is free. Orvis Store, High Street, Stockbridge, Hampshire, S020 6HB from 6-7pm. To enter or for more details email Simon Cooper.

About the One Fly

The idea for the River Test One Fly was conceived by Fishing Breaks founder Simon Cooper having competed in the American equivalent since 2005. Though he has never come close to winning, every year Simon makes the 5,000 mile trek to Wyoming with ever increasing excitement. For this is a contest that pits man against man and fish against fly – it is an unequal contest as the trout always win, but you can share the passion of one of the world’s truly great fly fishing events which is now held in England, the home of fly fishing.

But the clue to the difference to other fly fishing tournaments is in the name - the One Fly is exactly that – at 10am every competitor selects and ties on the fly that must last all day – lose it and you’re out! Points are awarded on a sliding scale according to the number and length of fish caught. There are no cash prizes – just the glory and kudos of winning.
