You don't indicate the amount of time that it's taken to build up to 7 miles. Aches and pains when you're walking and a day or two after your long run seem to suggest you may have overdone it on the 7 miler. Not a great problem providing you do the sensible thing (which you appear to be doing). Take it easy for a couple of days until the aches disappear then gently get back into it. Perhaps you could make your next week a step back week (where your long run is 3/4 of your usual distance).
Overtraining is very common when you've started running (or returning to it), I've tried to ignore my body's warnings in the past then ended up with long breaks and costly physio fees. The road to fitness is a long one. If you're following a schedule, don't be afraid to back off if you need to - your mind might know you're on a schedule but your legs don't!
Sorry to hear about the cold - how's it going mate?
Usual advice is: if it's below the neck(aches, fever etc.) give it a miss. At best, you'll over-tax your system and take longer to recover, at worst, you could cause long term health problems. If its above the neck, you should be ok to train but reduce the intensity until you start to feel better. Remember, a week off won't do much to your current fitness levels, it might even give your legs a much needed recovery period.
Jeoff, doing fine thanks, starting to increase the running phases between the walk breaks on the 10 miler (1 min walk every 6 mins. Will eventually work back to 10 min run intervals then eliminate the walks. Mid-week runs getting down towards the elusive 9 min/ml target. It's really encouraging when those first small improvements start to kick in!
Glad to hear the pain has passed - remember, if there's any niggles, do the ice thing (I once followed Paula Radcliffe's advice and sat in a cold bath for 10 minutes after a run ....once!).
Well its official. Today's the most depressing day of the year. 'Experts' reckon its to do with dark days, no cash and broken resolutions. Hope your resolutions (not to mention the baby cows) are still in tact! How's it going jeoff?
