Nice to hear from someone with a realistic aim based on a realistic training regime!
I have read any number of 9 weeks to go, no training, a bit overweight, never run more than 6 miles before threads. All you can advise them is, "start training 6 months ago!"
Your training looks great Stubbsy; good luck!
All I can add is don't get too carried away on the first lap; if you finish thinking that maybe you should have pushed a bit harder on the first lap then you have nailed it! It is very easy to get carried away in the first quarter of the race.
Just out of interest did you hear a 'pop', get someone to walk along behind you and observe whether your lower legs and feet are symmetrical (does one foot stick out?). Do you have swelling behind the knee?
Initially the advice for most injuries is rest, ice, compression, elevation (RICE) when sitting rest your heel on a chair so your feet are slightly higher than your hips (takes the pressure off your kneecaps).
There are knee braces that you can buy off the internet (Google 'knee brace') that may help, big price differences!
Seeing a GP is a bit hit and miss where outcomes are concerned, physio can be expensive!
I agree entirely Cal Jones, it is about what works for you. But fasted runs are a good idea.
I asked an elite runner what he thought of the Maffetone Method and he said 'LoB' but also said that he does 30 mile fasted runs and so does not think he needs to worry too much about his ability to 'burn' fat!
