Blimey we got busy. Fabulous 
I simultaneously think the Purbeck run sounds amazing and terrifying Sven. But it's far enough away to tip towards amazing!! Beautiful area but definitely 'undulating'
I agree with CherryMinx that it sounds doable gincamelbak but also based on not having done one yet!
The runningbug site has plans for most distances for beginners, intermediate and advanced so that might be worth a look Alice? I struggle massively with miles to km, so used to km so I think I'm going to in I'm for my HM. I did a 10k at that speed at the weekend - I refuse to call that jogging
. Are you doing all your running on a treadmill? I do interval training on one and find my speed is much lower than when I'm running outside.
How's your foot doing emummy? And your shoulder FiftyNine? I'd hunt out some Percy pigs, I'm quite partial to them.
What's your gut instinct Sirona? The training time is what I'd struggle with for a marathon but if that's your pull, it'd be a shame not to. Says me, see comment above about no half yet!
Your weather dos sound a massive challenge LadyCassandra
Hello bunique and Morris
10 miles does sound attractive Igotta, not seen many this way though. Must keep an eye out.
Getting the lie of the land is a good start Lonoxo. I like a few options of routes to keep things interesting.
