Most sources I've read suggest that your body can process at most 300 calories per hour during exercise. And a lot of sources suggest that you only attempt to replace roughly 200 calories per hour at best. You should be able to do this easily without any simple sugars. Your initial budget is much much larger than 1500 calories, you don't need to do a one for ...

You don't mention where you get your calories burn/hour rate, but 800 cal/hour is a very fast ride. 800 cal/hour would be around 220 watts, and that's a lot for 6 hours. When you are riding, some of your energy is coming from carbohydrate metabolism, and some is coming from fat metabolism. The ratio between the two depends upon how hard you are riding, your ...

"Nothing is so broken you cannot make it worse" - breaking a perfectly good chain in the field, miles from nowhere, with a light weight emergency tool, would be my very last resort. This will only work if the broken end is not too frayed. Remove the cable completely from the outers and the shifter. Thread the cable though the barrel adjuster on the ...

I would suggest your frame may be a bit small for you. I'm slightly shorter than you and I have a Scultura 906 in a 54 cm frame (size on the frame sticker says S/M). The longer stem may assist, however it may put you in a more race position which could lead to the neck pain. As for the calf cramps this could be a couple of things; 1) seat height too low, 2) ...

Why do you want to try and do this without sugar? Sugar isn't dangerous for you if your body is using the energy. I would also question the difference between getting sugar from fruit vs getting sugar from a protein bar. If you want high calorie/sugar intake from fruit, try to look for fruits that are higher in sugar/calories such as mango. You might ...

I broke a front derailleur cable at the top of a long climb once, leaving my chain stuck around the little crank for the descent. Luckily, I was able to find a small, flat-ish rock on the side of the road that I could wedge between my frame and derailleur in order to hold the chain up on the big crank. The rock shook free once or twice on the way down the ...

If the cable breaks at the shifter and you have externally-routed cables, here's what you do: Hand-shift the bike onto a big cog on the rear by pressing on the derailleur as you spin the pedals. Tie the cable around the front cable stay on the downtube. Adjust as necessary to get the bike to hold a gear.

I’m the poster of the original question. I thought several of the answers below made good points, especially @Fred the Magic Wonderdog and @Eric Gunnerson. But none quite put it all together the way I would have liked. However, by pulling together and organizing the many good points made by different people, I’ve come up with the following answer. Unlike ...

In my experience, eating any form of sugary food greatly increases the chances of a debilitating 'hunger knock' - all the more so if used to bridge times when your reserves are low. For me, sugar plays no part in any endurance diet. Reward, however, is another matter. Where I used to take a couple of (say) mars bars on every road trip, nowadays I take only ...

I have riden 7 Ragbrais and nener needed any sugar packets or candy bars. Assuming you have the time to stop and eat real foods and you have trained your body well you should have no problem. On Ragbrai we ride an average of 70 miles a day for 7 straight days. Longest day is a century. You do need to train to keep this up. I eat a full meal at least every ...
