Great North Run 2012: Can you help me with a target time?

[Deleted User]

Hi all,

I'm registered for the Great North Run in September – can't wait! 

Though not a club or serious runner, I want to have a go at a good time. I wondered if you could all help me determine what that is! 

I'm female, 29 years old, 58kg and a reasonably fit gym-goer and cycle commuter. Three years ago, I completed my first London Marathon in 4hrs26mins (with two toilet stops and a stress fracture!). 

Does 1hr45mins seem wildly ambitious? I realise it's a hilly course but I'm willing to put the training in! 

Thoughts welcome and appreciated. 

Also, I've had a look at the My Asics planner, which seems pretty good but I'm interested to know what other tools you all use to help plan and motivate. iPhone apps in particular. 

Thanks!
