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 ...

Clipless pedals let you pull up a bit and road shoes are rigid-ish, so you can get some more power from each turn (of course, you're using your muscles in a bit of a different way). This also gives a bit of a different pressure distribution than platform pedals (look at the layout of say, a Look pedal versus a platform pedal). In an off road situation, they ...

If you ride further or faster than you're used to, then some weariness in the legs is normal and should pass within a couple of days. I rode my biggest ride to date a couple of weeks ago and when I got home I nearly lost my balance walking around the house as my legs were a bit weaker than I expected. With a couple of days rest they were back to normal, ...

To answer your question directly, you certainly can use clipless over long distances. However, scientific studies have actually shown that clipless pedals offer no discernible performance advantages over long distances. They have shown that a small advantage can be gained on sprints, but that's about it. That said, many cyclists do report increased ...

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 ...

Great answer from James, let me just add a really quick tip. Before you go and read 1000 articles about riding position, just try the following: Raise the saddle a tiny bit. Most people ride way too low, and that just leads to knee problems if you start riding greater distances. I know it made a huge difference for me. Increase the cadence so you never ...

Aside from what the others have said here (with details on how to use clipless pedals), your original question was can you ride long distances in them. That is one of the things they are designed for. By keeping your foot exactly placed on the pedal, they maximize your pedaling efficiency. You foot never falls off the pedal. I rode over 3,000 miles last ...

You can absolutely ride long distances in clipless pedals. There are countless examples of this - at the extreme, look at any picture of a Race Across America participant, there is a very strong chance are they will be using clipless pedals of some kind (RAAM being a 4800km race, completed solo in less than 8 days by the winners..) Clipless pedals are ...

Like some of the other answerers, I have used clipless pedals over long distances. I have both Look pedals and SPD pedals, with the Look pedals, I have taken part in Audax UK events with distances of up to 400km in a 24 hour session, some of the rides being longer than this, but spread over several days. One I remember well was a 300km ride (187.5 miles) ...

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 ...

The advice previously given is very good and I won't repeat that. When buying shoes, go for a comfy fit, and not a tight squeeze, and they must not flex. Make sure your cleats are aligned so that your legs will spin comfortably. To get the most, your bike and riding position also needs to be optimised. Once you get used to cycling cleats on your ...
