I'm in the midst of training for the Dublin marathon on Oct 28th. It will be my 5th marathon but the first I will "race" others I ran just to complete and have a pb of 3:33. Training has been going well and have averaged 55-60 miles per week with a weekly long run of 2-2.5 hours. My original goal was to go for 3:05-10 based of my HM pb of 1:25:30. As part of my training I raced a HM yesterday, I was expecting to get a pb of about 1:24 but ended up finishing with 1:21:52. Based on this I was wondering if my goal marathon time was a bit soft? should I be aiming for sub 3? Must admit the idea of starting out at sub 7 minute miles is quite daunting!
I felt good in the race yesterday, though I did notice afterwards my heart rate was pretty high (AVG 180bpm) which seemed strange as I rarely go above 165 in training. The race I set the pb in was the new Forest half which is multi terrain and whilst not hilly has quite a few small undulations so would say not an especially fast race (winning time was 1:15).
