Thanks for the concise reply which I found very encouraging. I will certainly keep at it, run the 16 mile route aa few more times before looking at extending it any. I realise what you are saying about a marathon being more than twice as hard. As you say, once I am up to doing 20 miles and feeling Ok I will think about it!
Hi. I am what I describe as a seasoned half marathoner, Seasoned as I am 50 and have done about 10 HMs in the last few years. have been running for about 4 years. I can now do a HM in about 1:50
It got me thinking about doing a marathon. I have recently started training 80/20 so have run lots of miles at 'steady' pace. HM pace is about 8.30 at present so set off on a steady long run at about 9.30, pace felt great and as if I could run forever so could envisage marathon at this pace which would be about 4.00.
At 16 miles I felt fine in terms of fitness but everything was aching.... does this get better? should I carry on pushing distance? I expected to be able to increase distance weekly by a mile or 2 until I was close to 26.2 then be confident to enter a marathon.
I find myself changing shoes every 6 months, Annual mileage of about 1000 so roughly 500 miles. However, I run in Nike pegasus which can be as cheap as £50 so not exactly an expensive habit plus I can use the high mileage shoes to 'knock about' in.
Havent worked out HRmax as yet but at a guess I would say its probably 180. based on that my 75% would be 135. Had a half hr on the mill again but this time set it to 6mph. I knew outdoors it would be difficult to estimate a consistent pace for this test,
It seems to show an average of 131 which means I need to do my slow runs at 10 min miles. I'll try a couple of these slow runs a week with an interval and normal paced longer run at weekends and see how it goes!
