I'm doing my 1st solo aswell. Only decided to do it about a month ago. I certainly haven;t been training for 6 months but have been biking fairly regularly.
I did Dalby at the weekend and now got myself a bit worried as to how I'm gonna do this weekend.
Think I'm gonna take it 'Slow and Easy'. Got plenty of advice from some friends who have done this sort of thing and there's also a few of us doing it solo so may think that will help.
If the rain absolutely slings it down I'm retiring to the pit crews Gin Palace until it's passed :)
Good Luck though and hopefully see you out on track!
