That's exactly the right approach. I went along to last year's event with the children and they shouted their heads off, particularly for those that were struggling. I know it's a national champs but there's more than a whiff of novelty about it and I strongly agree that everyone should be allowed have a go. The fact that many regular racers will have put the good bike away and started grinding out the slow miles also suggests a more relaxed approach. The saturday morning slot should mean that there's no huge time pressure.
The course makes things interesting. Many of the twisty little evil boreens these things are run on don't give you much of a view of the road ahead. On this you will be able to see your five minute man. There's heaps of room for spectators too and a good bit of parking high up to make it easy to bring the little ones. I plan to be there supported by my sizeable brood. A decent lunch and plenty of ice cream will follow. It has the makings of a great day out.
These are a few photos I took when I rode up there back in March: http://ryansherlock.blogspot.be/2012...for-march.html
