I dont know how related this is but lets go…
I used to suffer badly on early morning rides, lacked energy, felt horrid during the ride and usually ended up with a headache sometime after.
These symptons never ever bothered me on a afternoon / evening ride.
Early morning rides I used to hydrate prior to the ride at home and drink plenty during the ride etc – I used to drink lots after the ride at home but always felt shit…
I started taking Vitamin C every morning and cos of this when hydrating prior to an early ride used the vit c tablet in water as my pre ride drink…
Since then I have had no problems during or after an early ride.. Its now part of my routine prior to any ride.. any thoughts anyone ??
