Thanks for the reply Alex. That's really helpful. One other question. I reckon I am running around 1,200 miles a year. But I've run in the same trainers for the last two years. They're a bit worn at the sides on the sole but they are comfortable. How often do you change your trainers? Once again, good luck!
Hi Alex. I'm really enjoying your posts -they're providing me with some great inspiration. I've done a couple of marathons but, to my shame, my times are slipping. I'd ideally like to shave around seven minutes off my PB, to get under 3:30. I run around 30 to 35 miles a week, mostly over the flat. But it's all pretty much at the same pace. I know they say mixing your training up helps but what would you recommend? Good luck in getting through to the final!
