The paper, one of whose authors is Asker, can be read here.
What caught my eye in subsequent tweets was that different coffees contain different caffeine levels.
This is somethng I learned nine years ago during one of my more bizarre commissions.
I had to drive the length of England to collect 25 coffee samples, mostly from motorway service stations. It wasn’t the most pleasant way to spend two days.
The Centre for Mass Spectrometry at the University of Sussex generously agreed to measure the samples. It’s the lab where Professor Sir Harry Kroto first identified the form of carbon now known as buckyballs and for which he received a Nobel Prize.
The results were more stimulating than a treble espresso/Red Bull cocktail.
They showed that the strongest coffee contained more than 25 times as much caffeine as the weakest.
So, if you’re gong to drink coffee to ride faster for longer, don’t drink a Nescafé Latté from the Sutton Scotney service station on the A34.
Better to start your ride in Cheshire, at the Sandbach servces on the M6,with an Espresso double from Costa Coffee. Vrooooom!
