Nine days to go till the 'Hook Ten'

I've got to be honest - my training isn't going well.
I've now got just over a week till the ten mile race, the longest one yet, and I've simply not been doing the miles I need to. I let myself get preoccupied by the idea of the triathlon I'm planning to do next month, so I've been cycling, started swimming and the runs I've been doing are generally around 5K - that's only about a third of the ten miles I'll be doing next week! I've also lost the regular long Saturday morning run with Iain.
As a result my stamina is definitely suffering and I'm running out of time to get it back. I'm sticking to my goal of finishing in 1 hour 40 minutes or less, but this could turn out to be a very painful experience.
