Thanks for your reply. Will arrange to see a physio just to be safe. Your advice about the 4th week comes just at the right time as this is the start of my 4th week so happy to reduce mileage a bit .
Re: core stability work - I have done at least one weights session a week for a couple of years now. and Re: drinking water on my long runs - yes I always do this. However I wonder if its somehting to do with my posture during running?
I am in week 3 for London Marathon and going OK so far. I am following a training plan for a 4.00/4.30 finish and completed a 14 mile long run on Sunday which is gradually increasng each week. However I have started to suffer a bit of lower back pain at night, espcially when in bed and just when I get up in the morning. However moving about soon makes it disappears and I am OK for rest of day. Is this just my body getting use to the distances?
Brief running history: I have been running for 2 and a bit years following life-changing death in the family. Slowly (very slowly!)going from strength to strength. Couldm't even run the school cross country years ago and always hated running!
Reason why we should train you: I would love proper, professional support - there's no greater motivator! Need a big push to get me to the next level.
Half-marathon goal: Sub 2 hours, preferably around 1.45 if I had the proper support! If not, I'll just be happy to finish - a great experience.
