Perhaps it is also a bit of that. But I'm pretty sure it's not my core that is weak, given the amount of core exercises I do and I mostly run off road, which I think is supposed to also help with your core.
Hi Booktrunk, interesting theory. 2 years ago I may have agreed this was true for me but not now. I climb a few times a week plank everyday (2 mins:30sec) and do circuit training once a week. My core looks to be quite strong, if seeing the outline of your abs and the above means it's strong.
I'm going out on my LSR tomorrow i'll try to focus on sortening my stride length and see what difference it makes.
I've just run for the first time with my Garmin 620. Like you Paris-Runner, lots of interesting figures came out. I was also in the red/orange zone for VO. I'm 5'3 and 53kg's. Apparently my VO was up to 12.4, average was 10.7, but down to 6 going uphill. I was doing intervals, besides the hill, but my speed didn't seem to have a big impact on my VO.
My cadence is the same as yours, 175 and ground contact slightly longer at 230.
Mind I did feel really tired on today's run so it will be interesting to see if that had an impact on VO when I run next.
Gosh is sounds like you guys got soaked on some of your runs today. I think I must have been very lucky. I did a 10k race at Longleat. It rained pretty much up until the start but then stopped and didn't start again until I was finished. so we had a 50 minute gap!
Mind I did get soaked on my long run this week on Thursday evening.
I second One20Four re the socks. I also wear x-socks and haven't had blisters whilst wearing them
