What's the quickest "boost food" whilst riding in a fast bunch? I am starting to ride with a bunch of cyclists doing on average 40 to 50k.
My personal average is around mid 30s to 45k/hr.
Aside from proper training, exercise and leg muscles, what food do you recommend to give you a quick energy boost to be able to keep up with the bunch?
I was told Mars Bars are quick energy sources, but high in the bad stuff. Any other more natural recommendations?
Thanks
Some personal thoughts/opinions:


If you're not riding much longer than an hour or so, you might not need much. Perhaps a sports/electrolyte drink that contains sugars will suffice and be convenient.
I use mainly cheap gel bars for a sugar hit, but they get quite boring and eat away at your teeth. Flapjack, oats, etc are good for a bit of variety but perhaps more appropriate for longer rides as they release energy slower.
Cereal bars can be quite dry and difficult to get down especially if you're a bit dehydrated.
Something with caffeine may be of benefit (caffeine on its own doesn't have energy, but it can give you a boost). I'd drink some strong coffee before the ride. Caffeine has a half-life of approximately 5 to 6 hours.
Trial and error is key!
