Don't stop running unless you can't run. The more you sleep the more you will want to. Just getting out and walking to the shops etc will help rather than sleeping. Just have a normal sleep for you. When i was working in the week i had no problem because i had to, but if did nothing on Saturday i slept all Sunday and Monday too. That's why i would like to do a cycle time trial on Sat afternoon despite only having 2 hours sleep after night work on Fri night.
I am pretty shocked to find out that your Doctor has said no running. Its a well documented fact that exercise helps. The less exercise you do, the worse you are likely to feel. I have only been borderline, but it is true when I had problem with it, i.e. sleep, eat, sleep etc all weekend that my breathing when i ran was impossible. And the first run i did, I would come back after 2 mins. Basically because if I don't run fast I don't run at all.
However, no problems now and i could only put it down to no gluten or next to no gluten for over 2 and a half years.
It really does depend what you are used to! I'm a night worker so I rarely go out in less than 5c and consequently I am always cold in less than that. If it's 3c or less I now wear bottoms. I'm on jury service so I went down my running club last Thursday. I wore the same as I normally wear for 1c and it was -4c. I was too hot, but I left my socks behind and used the thick socks I cycled there in. Maybe they made the difference but I had to take hat off. The other thing was , it was hilly and the pace was too quick for me. We probably set off at 4-10 per km instead of 4-20(which I normally do).
It's important to remember that one part of the body affects another, so if you are too hot you can take the leggings off.If it's flat you are going to be colder than if it's hilly.
What I think I was trying to say was that the shoes can cause running on the heels when you wouldn't have done that. I certainly have ran more in the forefoot since changing shoes. And certainly I have not pronated at all in them. Of course, what you are saying is that this guy could have a problem whatever shoes he is running in, but how can we tell if you say don't change your shoes.
So I would argue, he should give it a go and I would re-iterate that he should just do a couple of miles(at first) to see how he feels.
Interesting that Leeds Rob says he had a low cadence. I wonder what is meant by this, mine was 88(176 if you count both feet) in normal shoes and now is more like 92. But whatever the cadence, if you strike the ground further back in the foot it is perhaps obvious you will feel it in the hip area. There was an article recently in runners world that claimed every distance runner in a certain olympics had a cadence of between 178 and 182, so I am at least on a par with these.
The shoes may be the problem. In that they may be too high. I now have a pair of barefoot running type shoes(inov-8) and they are out of this world. With normal cushioned shoes they force you back on the heel(as that's where the weight is) and force you to run on the heel. It made me pronate and so i was shocked to find out that i had a neutral foot.
The only problem with these shoes has been calf pain, but be patient and you will be able to run every day. But in the early days make your runs short otherwise you may be off running for up to a week with calf pain.
In answer to the last post, i would say that nearly all runners should be running on the front half of the shoe and rather it is unnatural to be running on the heel. Before running on the inov-8 shoes i ran in my racing shoes and i found that i could ride a bike into work at normal speed just an hour after the run(19 mph, quite hilly). But if i ran in cushioned shoes, i had all sorts of pains, hamstrings, hips etc and they really affected me. It'd just incredible to only get calf pain after a fast run.
