DIY Sports Drinks

I'm too mean to pay the money for sports drinks in liquid or powder form, and it didn't take too much research to confirm that the core ingredients and composition of these products isn't that special. Granted, they make have some extra finesse in terms of proportions, ingredients etc at the margin, but it seems possible to get at least 80% of the benefit for less than 20% of the price (I do like my Pareto's Law).

So now I tend to fill my hydration pack with:

• 100ml concentrated orange squash OR 100ml sugar free equivalent plus 5 tablespoons sugar
• 1/3 teaspoon salt OR now - the recommended dose of Elete Water

... made up to 1 litre with water. This makes up to an isotonic drink which provides some calories as well as water and salt (plus other electrolytes if you use Elete) in "body" concentration for optimum absorbtion. You can increase the juice/sugar concentration to get more energy per litre (but may compromise hydration) or reduce it to emphasise hydration.

Caveat: I have seen recipes that claim to be similarly "substitutes for big buck brands" that have much higher and much lower concentrations of both sugar and salt - but the proportions here seem to be the most common agreed. Please make sure you're happy about the makeup of what you're drinking before following any of these recipes.

If you want to get a bit more sophisticated, you may want to look at using calorie sources other than granulated white sugar - glucose, fructose, maltodextrine etc - like this and this.

Cramp

I've had cramp a couple of times after rides - usually driving into the outskirts of Edinburgh after a Glentress trip is the timescale for it kicking in.

But it hasn't affected a ride like it did at the Penrith Merida MTB Marathon where it was a serious limiting factor. Reading up on cramp, it seems it isn't fully understood exactly why it happens, but there are a number of contributory factors:

• Temperature
• Hydration
• Fitness/fatigue
• Electrolyte imbalance

The first two aren't really factors for me, but I'd readily concede that fitness IS - and was almost prepared to accept that until I was fitter, cramp might be a perpetual problem.

Then I found out about Elete Water - mainly because their UK distributor Fine ADC have (had) an office in the same campus as my work office and James there gave me a few of their sample packs.

I used these during training rides over the next few weeks - I knew it wouldn't be a great test because I wouldn't normally get cramp then, but I wanted to be sure it wasn't going to cause any new problems.

... which it didn't. It has a salty-ish taste concentrated (which is not how you use it) but when diluted even in plain water there is no taste. I tended to add it to my DIY sports drink instead of the salt component.

The big trial came at the Merida MTB Marathon in Aviemore. I started to use Elete a couple days before hand in water throughout the day, and added it to the juice and water in my hydration pack on the day. I also took a small runners water bottle with concentarted juice and Elete Water in it so that 100ml of this would make 1litre DIY sports drink when topped up at the water/food refill stations.

I can't pretend that I had absolutely no cramp problems in this event, but they were massively better than at Penrith. My conclusion is that Elete Water dalt with the electrolyte imbalance part of my cramp problem ... now I just need to deal with the fitness part (which includes stretching) to get rid of it altogether.

Confirmation of that came when I did the same route again a couple of weeks later with Neal. Using Elete as before - and with a pace/gear choice that protected a niggling knee problem - I had absolutely no cramp during or after the ride.

It's not an inexpensive product - especially when you start buying the bigger bottles - but you use very little of it per litre of water. I got a couple of the little dropper bottles initially then a big bottle as you can (apparently) refill the droppers from the big bottle which is handy to take out on the trail with you for top-ups. I actually got a good price (esp with £1 P&P) from UK Bike Store but you should check for yourself.
