More generally, I don't think it's a great advert for Audax, reading about riders popping pills to stay awake while they ride their bike because they didn't have time to sleep.
The stigma around 'pills' is ridiculous. I can afford a pack of Tesco caffeine pills - they are cheap and easily stored. What is more expensive and time consuming is drinking coffee. There is no difference between caffeine in pill form and in roasted-bean-in-water form except the misplaced stigmatisation of pills.
Or for that matter in fizzy juice form, which includes Diet Coke at 42mg per 330ml can and Coke at 32mg per 330ml can.
And Tea though that varies by steeping time.
And chocolate too
And....
You really have to deliberately buy caffeine free products to avoid it fully.
The idea of needing 8 hours sleep is hokum too, invented at some point following the electric light, natural sleep patterns are much more complex and very personal too.
Something that was very obvious when Iroromono and I rode the "Kingdom Come" and "Snow Roads" perms this winter.
I cope fine with the long periods of darkness (and in the case of Kingdom Come until I sat down on the train); though give me a chance to sleep as on "Over the Hill and Back" and I have to get a time that matches by sleep cycle and rarely sleep "just anywhere".
Iroromono needed a snooze on the Snow Roads at 1am and similar on our abandoned attempt at the "Central Scotland 300" as that's his sleep pattern.
