It was your first proper race, I think you did brilliantly.
This is my 8th or 9th season and I'm still finding areas where I need to improve, so just keep racing, don't be afraid to ask questions and when you identify an area to improve seek advice on how to get better at it.
I've just seen John Mx's photos, we so need to work on your bike carrying technique.
I need to work on my starts, if my opening lap had been ten seconds quicker I'd have been up with those racing for the top ten.
