I'd say that you hit the nail on the head when you said that the training plans assume that 2:30 runners won't be training particularly seriously. Sounds a bit patronising really.
If you're already able to run 10, then you've plenty of time to build that up to 15 miles. I would say that this is a very realistic target to go for. Find the best looking plan you can, and just add to the weekly 'long' run to achieve this. The only thing you might need to watch for, is whether you'll be properly recovered to safely do the next run on the plan. If you're doing 12 miles on a Sunday, and your plan asks you to do some hard work on the Tuesday, then you might need to adjust the timing of that session... or reduced the intensity/length of that session to make sure your body has time to heal.
Make sure that the big majority of your long run miles are run really slow. At least 1.5 minutes per mile slower than your target HM pace.You need to use them to develop your slow aerobic systems. You can use other sessions, like a weekly tempo run, to develop the speed side of the equation.
Ha... IMO, on this occastion, the knee-jerker is you, I'm afraid faith's daddy.
Do you really think that we should put concrete paving under all the climbing frames and slides? Maybe we could put razor-wire between the monkey-bars. Children would soon learn how to manage risk.
Not one person on here has said that we should remove risk from play. I suspect that most parents on this thread, like you, try to get the balance right. You're just being a bit overly keen to criticise those who think that removing completely unnecessary risk is a decent idea!
Booktrunk... I can't tell you how glad I am that you posted this. Seriously!. I was genuinely worried that my teenage daughter had been using my laptop to do searches on the subject of abortion pills.
You will have noticed that the internet is very clever at advertising things related to your recent searches. For example, this Tory MP got caught out when he pointed out some dodgy businesses advertising on Labour's website.. only to then be told that the advert was driven by "Google Adsense", and had appeared on his computer alone, because he had presumably been searching the web for "Dating Arab Girls" ! Ha Ha. http://metro.co.uk/2013/03/18/conservative-mp-gavin-barwell-in-date-arab-girls-twitter-gaffe-3546925/
I'm very very glad that it's not just my computer that's got these adverts all over them!
