My clubmates have the opposite problem. When I first joined no-one had GPS, but since we all started getting them we've discovered that the 'Gedling 10' is almost 11 miles and the loops we run in the country park are each at least a mile longer than we thought. Many years ago I accidentally ran my first 20 miler as the guy leading the run thought it was 16 - 17 miles.
KR - Wardi (Sub-3 and occasionally Sub-3.15 threads) currently has a broken rib and is managing easy plodding with the aid of prescription painkillers. Probably worth a trip to the GP or walk in centre.
It's a lovely calm day today, so typically it's a rest day! I could run of course, but I have to keep reminding myself that this is my rest period and I'm already doing parkrun tomorrow and Saturday and booked in the gym on a free pass on Thursday and Friday (3 classes booked, plus I will almost certainly use the treadies while I'm there). I may be doing a tough long run on Sunday too, though I need to check out what's happening with that.
AW - at least you have routes you can run when you're away. I didn't take up running until I'd long since moved away from home, so I really don't know where to run in Newcastle. I end up doing really boring routes on pavements to places that I used to drive to (so I know where I'm going!) or just run on the Town Moor (home to parkrun and the Town Moor Marathon).
