Matt - i did a similar thing to you and went from 30 to 50+ mile in the first week, thought i would be fine as i did a Autumn marathon and was use to regular 60+ mile weeks.
Started getting heel pain/sorness and looks like i have PF, when to the phsyio and im off running for at very least another 2 weeks, think i will now skip a spring marathon and try and get rid of this PF and hopefully concentrate on shorter distances.

Couldn't resist another marathon so did my first session tonight was about 20secs per mile off my LT pace so lots of work to do, will be playing catch up for a bit as my weekly mileage has only been about 20 miles for the last few weeks. I am in our club ballot for a VMLM place on Sat night so if i come out of the hat that will buy me another week. Great range of pace here
