Couch to 5K

So I was reading the above post (instead of doing some work - this site is great for procrastinating). Needless to say I've never heard of any of this stuff before - age grading, etc.

Anyway, a few years back I did a Race For Life 5k with some friends. My friend and I trained for several months by doing about half the distance - the only time I ran the whole 5k was on the day itself, and it took me 40 minutes. At the time I was amazed that I'd done it, and I still am. Knowing that I did once run that far has helped to keep me going while doing C25K.

I was 35 at the time. Plugging the figures in to gives an age grade of 37.4. So with a bit of trial and error, I have worked out that now, at 43, I might expect to do 5k in 41 mins 45 seconds. Which is interesting.

How did you work this out please? Sounds interesting!


I went to and put in what I did before - i.e 35 years old, 5k, 40 minutes. That gave me Age graded: 37.4%. Then I changed it to 43 years old and increased the time until I got the same age grading of 37.4%.
