Take ur time to decide, I wanted to do overseas races and next year will be the time.
My biggest hurdles for HM will be whether I might cramp out later into the run and gut issues (which is highly unlikely for morning runs).
My pace is there, I still have a few sharpening workouts to do. I am thinking of peaking with the 15km HM workout (4k @ 4.08 - 4.12, 1k float @ 4.35 - 4.40) x 3 in 2-3 weeks time.
My last week workout was 1.5k @ 3.58, 4.00, 4.03, 3.58, 1.5k float @ 4.28, 4.30, 4.30. Slowly, cut back on the pace and increase the interval distance.
I will train for 3:20 after the HM, I will think about it more in Jan.
D is what I can achieve now in Sg. C is what I think I can achieve overseas. B is upper limit of what I can achieve overseas. A is best case scenario by the end of the year.
My conversation with my friend was that he recommended me to run HM because he was worried I might lose my fast twitch strength if I transited too fast from HM. Since I had to wait for 30k people in the queue today, HM was sold out. I made the decision to go for the FM for the experience.
After a bit of reflection, I realised it's possible to maintain fast twitch by doing strides (Kiplimo does this in his weekly workouts), short distance intervals (1k repeats at 5k pace) + doing longer warm up and cooldown to make up for the short intervals mileage. There are ways to get around this, so I am not too worried.
In the 6 months:
1. Get used to 70k+/week of running average, with long runs going up to 30-35km and peaking at 80k+/week.
2. Try energy gels while maintaining my running form and fix my hydration regime.
3. Figure out true marathon pace, highly likely <5.00 min/km based on consistent long runs. Unsure if it's 4.45 min/km.
