Thanks
How I decided my pace was after doing a half marathon in Sept. in a time of 1hr 38min(04:41 per km) in which I felt reasonably comfortable, I used this as a measurement against the Marathon itself. So doubling that would give me a time of 3hr 16min, and then add 10 minutes or so to allow for the extra exertion etc of the full marathon would give me a time of around 3hr 26min.
Because my training had gone so well I felt confident that a time of around 3:24/25 was possible and achievable. So this gave me a pace of 4:50 per km
and is the pace I decided to go out at.
Below I did a little race report for the Dublin Marathon 2015:
Chip time: 3:28:22
Found it very tough mentally. Had to make an emergency P stop into one of the portaloos on chesterfield avenue which cost me nearly 3 minutes! Was trying to keep the 3:20 pacers in sight before then. When I re-amerged the 3:30 pacers came flying by. Damn. Had to revert to plan B. So made the decision to stick with them until after the 22 mile mark and then see if I could achieve my B goal of anything under 3:30. Thank God for the support along the way and especially from the 22 mile onwards. Really helped me to dig deep to get in at a time of 3:28:22. So still got a PB of some 7 minutes. This was my first Dublin marathon, my second after Frankfurt last year(3:35:56).
Frankfurt was a very flat course where as Dublin had several uphills but Dublin triumphs in the way of spectator support along the way. But had a very happy day and my future plans are to get under 3 hours, I hope eventually.
