Well done for battling on Steve and well done Yasunaga.
I had long distance duathlon champs yesterday - 15k run, 60k bike, 7.8k run - last race before Edinburgh. Ran run1 at 81mins half marathon pace (4th), run 2 at 86 mins half marathon pace (2nd) and came 5th in age group overall. Hopefully 3hrs is within reach if all goes well - certainly don't want it hot.
Congratulations Alex, Denis and Cookbox and everyone else who did Paris in a great time. Shows what consistency in training can do.
p.s. If you can run at the paces consistent with a 3 hour marathon and can cycle reasonably well you have a good chance of getting into a GB age group team for long distance duathlon. Check out the British Triathlon Federation website if interested.
You've got every reason to be confident and relaxed.
I've clocked up 40 miles in the last 3 days but felt slow and rusty after a week focussed on cycling. Was a hard week of 600 hilly miles so hopefully! it has built some useful endurance for running as well as massively helping my cycling.
