This might interest some people.
Myself and Tim Healy recently completed a speed circumnav of Achill. I am trying to find out who else has done it. I only know of Tadgh de Barra and Ali Donalds successful attempts. Does anyone know of others?
If we can get a few times together it will be listed on the performance sea kayaking website as a challenge and it might attract more attempts.
