Urgent Advice Sought

[Plodder]

It has been along time since I logged on to the forum I do apologise!

The reason I have come in from the cold literally is that I have developed a really frustrating niggle in either the achilles tendon or the muscle alongside it in the back of my right leg.

The frustrating and annoying thing about it is I was just beginning to real feel I was getting somewhere and had completed 18 miles last Monday.

The history of the ache, pull, tear is as follows. I am following the runners world sub 3.45 marathon program and as mention completed 18 miles in 2.20. on Monday in a relative new pair of trainers.

Feeling good after arest day I then pulled on an old pair of off road trainers and completed a 10 mile run on Wednesday.

On my return I had the fore mentioned ache.

I then iced and rested it for 2 days to see if it would recover to no avail tried it out on saturday ached rested it completed a 5 mile on Monday ached afterward.

Tuesday I had a massage felt good ran this evening nice easy 7.15 pace managed 2 miles then the bugger flaired up again.

Any suggestions bearing in mind have a place in the Winchester 10k on Sunday ( suggested by RW) Fleet half coming up and the London which I want to do well in .

Please help
