Just worked this out for myself, and like Cougie, I averaged 23 miles a week. Also like Cougie I cycle and swim (triathlon focused rather than just pure running). Unlike Cougie however I didn't go sub 3.15 - but my 3.28 was a PB by 23 minutes in my 2nd stand-alone marathon so I was totally pleased with that, still with plenty of scope for improvement.
I went +30km 5 times in training, longest run 36km (22.5 miles)
