These cheap frozen treats may be the maddest way we’ve ever seen to avoid muscle cramps, but they are on sale for Amazon Prime Day if you’re crazy enough to try them

As I write this, it’s the tail end of a four-day Amazon Prime Day event, and in the UK at least, there is an ongoing heatwave. I am planning a very long ride tomorrow, and so have electrolytes on the brain, and as such, trawled Amazon to see what was available.

For more conventional athletes, there are products like the Styrkr electrolyte tablets on offer, and for convenience on the bike, they are hard to beat and are currently on sale.
