Wabo - good 10k you must be pleased.
AF - horses for courses - if he tried to run 100mpw he probably would have broken down. I have a relation who was a very good 800m runner, he had enough speed he didn't need all the extra miles - he was a race horse the extra heavy miles broke him down.
Tom answered your question perfectly - "by the time he reached the final he was a spent force - (why because he lacked endurance), while the old plodder won 5k, 10, and the marathon".
It's like anything, getting the balance right, knowing your abilities and weaknesses and working on them.
Stickless - good to see you still going well.
Mava - congrats - well done. The next bit is going to be tricky, getting yourself up for London. Just make sure you look after your legs and your feet.
Plenty of gentle massage, and go for short walks, let your legs come back, maybe a 20min - 30min jog middle of the week, then a few more short walks, and you just might get away with it. You have done so many long runs, you have heaps of endurance, you just need to let your legs to be able to run for you.
Good luck.
What: Short walk with daughter and gdaughters and Mae - suggesting it to Mava, (hope it works for me)
Good running everyone.
