4:36 if anyone's interested.I didn't adopt a run/walk, but shaved a minute a mile off my normal comfortable jogging pace, so was pretty conservative. Went through halfway in 2:08. This paid off really as only had a slight wobble between 19 and 22 miles where I had to walk because of looming cramp. Was really pleased with the outcome considering, and has given me the motivation to train properly next time to try and break 4 hrs.
well, I kind of listened to the advice on here and tested I if could run/walk effectively. Jogged 9 first then walked the first 0.2 miles of the next 3 miles and called it a day there. Could have carried on like this pretty much indefinitely (it seemed) but my feet have softened up quite a bit with the break from running and my calves were beginning to grumble a little. So no doubt Sunday will be tough, but I think I should be able to get through it.
Jog 20 v slowly, regroup, then walk 6 was the original plan. But I will try the regular walk break method instead.
If I employ this method on a training run on Saturday, does this mean I could then extend this training run a bit further, to perhaps 15 miles. Bearing in mind I have no cumulative fatigue from training, and I will have 8 days to recover?
