I'd advice hitting MP in the first mile - most people go a fair bit quicker than MP in the first couple..... even splits are the way forward. Very hard to negative split and if you did chances are you could have run the first half more efficiently.
We were running chalet for others, but have developed a business plan for our own differentiated chalet - whether or not it will be implemented remains to be seen
Remember the effect of 1000s of other people running and those on the side lines can't be simulated in training - makes a massive difference.
You can do a marathon on will power alone - its just a question of how long it will take you to walk pain free afterwards
I've only done 3 so far -one in a silly furry animal outfit for charity - one to see what could be done, and the last one taking it seriously and gunning for a time. Each very different.
Its the journey not just the end result for me -and now after Barcelona the idea of doing a Marathon as part of city breaks with friends and families makes it even more enjoyable.
I'm pretty certain this time round it'll be ok until 20 miles and then the wheels will fall off - we'll see. In the last one - about 90% of people went off too fast - and were treading water by 22 miles. If you can be strong in the latter miles you will get a massive lift from passing so many people.
Also have seen people trying to pack in far too much nutrition - 10 gels! really? I've experimented and found that 3-4 works quite well, with a gulp of water at each feed station.
James do morning and evening legs raises on a set of steps .... toes on the step - heels off the edge then lower heels gradually and then push up onto top toes. Do a set of 10 in morning - set of ten in evening ... but to feel depending on stretch and feel. (To be fair everyone should do this regardless of injury) ..... then foot flat with end of foot slightly away from wall and move knee towards wall keeping foot flat until knee touches wall - move foot back until comfortable stretch achieved.
Massage the painful area - bit of ice, and shorter runs.
I have a similar issue that has been recurring over the last 3 months ... this ritual seems to have helped although not eliminated the issue. I have inflexible ankles which is partly to blame.
One of the issues with Marathon training is that the training plans become such a big focus with x number of long runs etc, and having to run 20 miles etc .... if you get a niggle at 15 and push through regardless for another 5 miles.... then it could end up doing more harm than good. Wonder what the percentage of people lining up for the Marathon with minor injuries it! (must be quite high) ....
Swimming and a bit on the bike can keep things ticking over nicely AND help to release other tight areas. Hope that gives some ideas.
