ok, I'll bite on the nutrition part..been wanting to DIY on-bike nutrition for a 40 mile ride I have been doing recently:
Gravel ride to trail: 12.5 miles
Six Mile out (eastbound) and back (westbound): 13.5 miles
Gravel ride back: 12.5 miles
I bought two 3.5 oz flasks that I want to fill with DIY carb/sodium mix to try to ramp up the speed on the gravel parts of the ride (not trying to go fast at 6mile due to oncoming taffic and peeps riding without helmets).
So far I tried filling the flasks with maplen syrup, about half teaspoon of salt and lemon juice to cut the sweetness, but I overdid the lemon juice and it had a bit of a kick I didnt like.
Is anyone trying DIY nutrition experiments like this? I was wondering about mixing in honey but that's fructose so needs work in the liver....might try that next time.
