Don't think I could bear to caffeine deplete. Have def learned to not overstuff the day before though following a disastrous muffin, lucozade and bagel binge the day before VLM a few years ago. I recall standing at the start feeling distinctly blobular
Abbers - it's manchester I'm doing. I'd love a PB but will see how the early miles go. Marathon number thirteen for me I think
so are you just on normal diet for the 2 or 3 days pre race BB? I wonder how long it takes for the glycogen to be used up assuming you're not running much....
Cardiology opinion and maybe echo would allay all your concerns I'm sure. Good luck! Would probably be a bit of a wait on NHS but could prob see someone locally in a week or two if you're happy to pay....
ECG gives good info on electrical activity in the heart particularly in respect of pattern of electricity passing through the heart muscle,rhythm and - to some extent - structure of the chambers of the heart
You've probably just got an innocent flow murmur and are absolutely fine to run but you can only really comment on the flow of blood across valves ( ie exclude serious causes of murmur) with an echo
Did the doc say what phase of heart sounds he heard the murmur during?
