Unlucky Arnie. Unfortunately the art of marathon means running long distances which break up muscle fibres which then heal stronger and then repeat the process the following week until we all turn into endurance machines.
There will be no short circuit for you - I think with just 3 weeks to go you'll just have to try get some decent mid range runs 13-18 milers in if the injury allows.
The next 2 weeks will be crucial. If the injury allows and you can get some quality runs in, do virtually nothing in the final week in order to let your legs recover.
By now your CV fitness will be at a good base level but it's the 'time on feet' lost that will really affect your run. A colleague had a similar situation for London, should have hit 3.20 but ended up doing 3.56.
Stoker: I played in our annual pre-tournament 11-a-side game last night at the football club. The old magic kicked in. We were 4-1 down, I scored 4 (including a penalty that I dived handsomely to get) and got us to 5-all and won a free kick at the death which we scored to win 6-5!
Feeling pretty pleased with myself. 44 years old and my first proper (cunning) dive in the box, my first 4 goal haul and first ever 11-a-side penalty kick.
Went home and setup the Garmin. Champion!
