K, you're not older than me, you're younger, so no worries on that score!
Thanks for the info re asthma, I'm breathless just typing this, so
but I'm sure it will get better - some day!
Good luck with your training, one thing that I would say is that if you can get some miles in before starting the marathon, then I think that that would help. A lot of people go from 0 - marathon miles and it's asking quite a lot. If you're going for NY, then you'll have plenty of time and with the HM in the middle, you should do really well.
FWIW, I would concentrate on building up a good weekly base if you can, the minimum would need to be around 25 - 30m (is that feasible?) then when you're comfortable doing that, look at marathon training, but possibly not starting at the very beginning. I know that a lot of bods on here have adopted that approach and it works well for them, avoiding the niggles that sometimes come with going in cold.
Well, that was the advice given to me and I've followed that, leaving my first marathon until now. I've got a good base of miles and I know that I can comfortably do 20m, then it's only another 6m after that
. I've found that HR training works well for me, it might be something to look at as if you're coming back after injury, you need to be careful and HR training works on the basis of more, slower miles, not depleting glycogen stores. I've had major foot surgery and was being conservative, not wishing to incur further injury, so was only running about 30m (3 / 4 days) per week, but by doing HR training, I've been able to increase mileage and run 6 days without (touch wood
) any problems.
