Hours per week running?

[Ally]

I stopped racing around 18 months ago and now go out for the sheer love of being on the hills, I average around 24 hrs a week and on average do around 130K a week.
So far this year I have done 5000K distance with 117,500 metres of ascent.

That's a lot of hours, no wonder your stamina is good! As other's have said, the kind of work you need to put in depends on what you want to get out of it. Broadly speaking more is better for just about any race distance but if you want to race loooong then you'll probably struggle if you can't get the volume of training in.

I've peaked about 12hrs/wk this year which is less than last year but with more quality work and some gym stuff besides. Hopefully get more mileage in over the winter. 2,667k and 152,432m vert for the year thus far. You know, roughly.
