Stepping in here on a nutrition point.

Even if you cut out sugars throughout your daily life- don't cut them out on the bike.

When you are on the bike, the calories you take in(via liquid, gels,etc) and transferred into energy almost ASAP (granted you are riding for over 1.5 hours, longer ride or harder,etc.- does not count for an easy recovery ride)

There is a reason that energy gels, drink mixes, etc. are what they are- your body turns it into fuel asap.

When you hit the point of bonking, you have gone to far- it is your body telling you it needs energy to keep going.

I eat almost no sugar in real life- I use agave or honey in coffee and that is it, I eat pretty paleo(with the exception of some ezekial bread a few times a week) but on the bike I feed my body what it needs to perform at it's best.

That might mean gels, blocks, home made bars, drink mixes, just this past Sunday on a slow 5 hour ride(75 super slow miles) I had to stop at about hour 3.5 due to me bonking at a gas station and I had a Dr. Pepper and a Snickers.

Sometimes I just need some fig newtons or vitamin water at the gas station.

Also if you are riding over 3 hours, you should be taking in protein also(I get eggs at a gas station if I have a chance to stop, since protein mix doesn't sit well in the Florida heat in a bottle and bars tend to melt).

If you want to keep it so you know what the ingredients are- check out www.nomeatathlete.com

There are some great recipes on there for home made gels and bars(I eat meat, but on the bike you don't usually want meat- so great ideas on here).

Or, if you want real food- you could take a small baguette with you, some butter, honey and ham in it and snack along the way(sodium, sugar, carbs, protein).

Just please please please realize that taking your body off of all sugar while riding is detrimental to your improvement.
