So two days after my first half marathon and I've had time to reflect and think about what I've learned. I want to record this here so I don't forget about it!
* Porridge and banana works really well as a pre-long run breakfast
* There is little point in running one of your fastest miles in mile one of a half marathon - better to save this for a 5k or 10k race
* It's easy to get carried away at the start because it 'feels comfortable', slowing down takes discipline but will reap rewards later on
* One gel an hour was enough for a half marathon, I may need to increase this as the mileage increases
* High 5 gels are definitely my favourite, for consistency if nothing else
* Too much Lucozade Sport makes my mouth feel quite sticky - I need to follow this with water
* Switching from a 9:1 to 8:2 strategy helped a lot in the later miles and made only a little bit of difference to the mile times
* Always trust your Garmin. It is right!
* Active recovery works - walking around in the afternoon helped to stop my muscles from completely siezing up
There are some questions that I still need to answer during the second part of the training:
* Can I survive 26.2 miles on gels alone? Will I be able to stomach it?
* What made my feet cramp up from mile 11 and how can I stop that happening again?
* Can I do 26.2 miles without any music - there will be a lot more going on on the streets for the London Marathon but a bit of music might provide a bit of a lift during the tougher parts - I know it would have helped on Sunday
* I averaged 11.50 minute miles for the half marathon - what is realistic for a whole marathon? I need to know this so I know if I am going off too fast at the start
* My hamstrings really weren't that happy from mile 8 onwards - how do I stop that happening again?
There's plenty of miles to be run in the next 9 weeks that should allow me to answer some, if not all of these questions. Some I will probably only answer for sure on the big day itself!
