Got that covered

. When working nights I usually hurriedly consume a largish family evening meal before rushing out the door to cycle a fast 10 miles to work. I never have any issues producing the required effort or keeping the food down/in

.
Conversely, on day shifts I leave early (5.30ish) after just a mug of coffee and do the same ride/effort and continue to work through to around 9.30/10.00 before eating any breakfast, just using my bodies reserves and this doesn't feel physically much different.
When doing longer rides of 100 miles or similar I stop to eat around lunchtime after 40-60 miles because I am feeling 'peckish' rather than feeling weak or exhausted due to hunger. I don't know if I reach a point where fuelling becomes an issue because I don't let that happen and just following the 'normal' meal routines has proven enough to support my cycling adventures.
Obviously this may be completely different for my partners on the LEJoG trip?
