As running is going OK, I had this idea of doing another marathon next spring, but ideally without doing 5-6 days per week of training. I got talking to one of the other football dads who swore blind that he ran a 3.10 marathon last year aged 50 off 2 days of running per week plus regular cycling, but doing all his runs fast - at marathon pace or faster.
This makes a lot of logical sense to me - if I already know how to run a 4:30 pace for 10k, then I just need to keep increasing the run length at that pace until I eventually hit 42k.
So I'll give that a go and see how I do. The only major flaw I can see is the 30k+ runs, which could be so knackering that I need more than a week's rest in between, or bugger up my legs for good.
The key question is what the base speed should be, but I think I'll go for 4.30, which equates to around 3.08 for the marathon. Or should I go faster...?
