This 160km, non-stop race round Lac Léman (Lake Geneva) was the first big expedition rowing challenge I actually rowed (rather than coxed) in.
Completing it changed my whole mindset, gave me a belief in what I could do on the water, and taught me the No.1 rule of long distance rowing, as far as I'm concerned.
When I set off to cox most of 90 nautical miles across the Irish sea (my first ever rowing expedition) my idea of a long outing was less than 2 hours, and on a river.
But somewhere along the way, after the fabulous sunrise, the sight of the Welsh coast after a night of rowing out of sight of land, and then the arrival on it made me realise the incredible sense of achievement you could feel, despite being second last in a race (and I'm normally a bad loser).
