The race organisers generally get it right when it comes to the start list. I recall struggling in practice for the 2013 Classic TT races ending up almost at the back of the grid (not my normal position). It was a real struggle for the first couple of laps passing riders I'd normally start ahead of, which increased the risk factor. Fortunately it went well but what I learned was given the chance to go with your seeding and minimise the risk. But then again I'm no Michael Dunlop!
