What to drink during an adventure bike trip

[samueleuk]

In previous posts on my blog, I discussed the importance of being well hydrated to prevent mental fatigue, and how to assess hydration level. The next question is what to drink during an adventure bike trip. Is plain water enough? Or should we add some electrolytes?

To answer this question, I have got in touch with Dr Ricardo Costa, an expert in sport nutrition at Coventry University. Furthermore, Ricardo has competed in the grueling Marathon des Sables. In this multi-stage ultra-marathon, athletes run 251 km (156 mi) at very high temperatures for six days. So I am sure Ricardo knows well the science of what to drink when sweating profusely for several days in a row.

This situation is similar to riding a motorbike for several days in hot weather. Although physical exertion is much less compared to a marathon, wearing an helmet and full riding gear greatly impairs sweat evaporation and its cooling effect. As a result, even more sweat is produced. So loss of body water through sweating is likely to be very significant during an adventure bike trip in hot weather.

Fortunately, with the exception of sodium, the concentration of electrolytes (e.g., potassium and magnesium) in our sweat is extremely low. This means that even during a multi-stage ultra-marathon in the heat (40C) serum electrolyte concentrations is maintained within normal range (Costa R, personal communication).

Based on this and other research, Ricardo's practical recommendation is simply to add a pinch of salt for every 500ml of water when we ride in hot weather and drink a lot to ensure a good hydration level. The extra salt does not have to be added to drinks. It can be added to food as well. This simple sodium supplementation will greatly reduce the risk of hyponatremia (meaning "low sodium"), a very rare but potentially fatal electrolyte deficiency that can occur when people sweat a lot and drink an excessive amount of water.

The above recommendation is valid for adventure bike riders consuming an adequate diet. However, data about weight loss suggest that many riders significantly reduce their food intake during an adventure bike trip. In these conditions, taking a daily multi-vitamin/mineral supplement that meets 100% RNI (e.g., Centrum or similar products) will act as a safe guard against other potential electrolyte deficiencies.

In future posts, I will discuss whether it is a good idea to add glucose or other soluble carbs to our drinks. In the meantime, please let me know about your experience with sport drinks if you have used them during an adventure bike trip.

Cheers

Load of cobblers.

What's wrong with five pints of and a kofta after a long days ride? Although fair play, you did say the salt could go on the food.

Electrolyte drinks are a complete rip off - useful for babes with diarrhoea and extreme athletes only.

Ride on.

Just to clarify that I don't advise to use sport drinks. I am just curious to know if and how they are used by adventure bike riders.

My suggestion is to check your hydration status, drink water as needed, and add some table salt if it's hot and you have to drink lot of water to keep you hydrated. Table salt can be found all over the world and does not cost much. So no rip off and very convenient

Drink at night, but make sure you drink a glass of water before bed so to avoid dehydration effect caused by the diuretic.

In hot areas I drink 3lt water minimum a day(cold wet days this drops to around 500ml) and if I have not stopped every hour or so for a leak, then I am not drinking enough

Take some nice tasting rehydration powder mix with you, what you can buy on the road tastes like salt for the most part and when you get the trots, and you will, then it will become useful

Water, like what fish poo in (regardless of salt), Yuk, no thanks

I'll have a cup of tea with milk until it's gone then lemon every couple of hours. The last slice of lemon is for my G&T when the days ride is done then it's whatever or wine goes with the local grub. Nice cup of tea or hot chocolate sets you up for a decent nights sleep.

I wonder how Hillary and Livingstone managed? No funny tasting lucazade for them.

If your are on a real adventure there is no way you can get sport drinks. You will be happy if you find plain water and you will be thinking of adding chlor tablets to it if you drink from a river.



Lone way up...eine etwas andere Afrikareise - Teil 3

Ayway to carry some salt (together with a fork if you dont want to use your fingers) might be a good idea. In many places even salt is not available and Nsima tasts much better with a little bit of salt...

I agree with Tobi, if you are actually travelling in far flung places you drink whatever you can get, usually water sometimes flavoured with tea or coffee, the occasional coke and a or G and T in the evening if you can get it.

[JetJackson]

But do you think travelling through say Africa, one should take rehydration salts with them on the trip?

Here is a thread of what can really go wrong in the heat if not managed properly.

I think heat exhaustion is more the serious issue for adv riders than dehydration.

Sam, would be great to see a post from you on heatstroke/heat exhaustion etc.

Try buying it in Timbucktoo?

And if you mix it with water .. and drink it later .. the residue promotes the growth of bugs in the container .. not good. Plain water is simpler, greatly reduces problems with bugs in the container and cheaper. Don't know how stored tea will go... any tea drinking bugs?

If you need more thingys - get them in your food .. where they should be. Bananas are good for bicycle riders - containing potassium etc and fairly available in hot climates.

My experience is that no matter how much I drink, water just fills my stomach up and I dehydrate. If I mix sport drink with the water at about 50/50 or less then I seem to absorb the water quite well. Straight sport drink makes me thirsty. Water makes me bloated.

Not "adventure" riding, but trail riding in 40-50 degree temps.
