I went to spectate at the first IM Bolton & vowed never to do the race. Some factors meant I changed that decision this year - I loved it. Found it well organised, well supported & an interesting course. I was trained for endurance rather than speed & honestly didn't find the course tough - I was just slow.
I did Outlaw in 2012. I pulled out during the run due to injury but that didn't cloud my judgement - it just wasn't mdot.
but but that's just my view. People get different things out of events.
