I now have a cycling commute with some reasonable hills in it. I find them really quite difficult.
I know that cycling miles do not equate to running miles in that you need to do more miles/spend more time on the bike. So when I have trained for long events I have tended to view my training in terms of hours.
With regard to ascent though; is a ft of climb on a bike worth more than a ft of climb when running and is there a rule of thumb I could use for conversion.
