Nope - I'm just trying to go to 13 miles. I built up to a couple of 13 milers in Feb/Mar, then deliberately scaled back my running for a few months in deference to hitting the gym and bulk up a little. Since start of July I've been gradually building back up for the HM, but I've also got an extra 9 kg to carry round with me. While I'd be a very delighted 46 y.o. with anything under 2 hours, I'm mainly just wanting to get round. I thought I was doing as you say, running slower to try to increase the distance, but I just seem to have a running pace that my body naturally slips into. My per mile average yesterday was pretty much the same as I do on a 5 or 6 mile run, and that was with a monumentally slow 11th mile.
Nope, do you think I should?
Thanks for the interest from both of you, I don't really have any running experience, just took it up for something to do after 30 years in basketball, which is a totally different dynamic physically, so I'm a real uneducated amateur.
