Post-swim ice coffee in enormous SportsDirect mug
Make a thick paste from two teaspoons of instant coffee and a tiny bit of hot water, add sugar if that’s your thing, pour over ice in an enormous mug that you got for free when you ordered a pair of trainers from SportsDirect.com and top up with sparkling water. Ice cold coffee goodness. And you can put rum in it if you like.
I didn’t say it was fancy.
