This is dangerous thinking.
Last week I started a ride with 59 other cyclists.I rode the last 80km solo.

ETA attach the pump to the frame with zip ties or tape of some sort.
Yebbut that was audaxing, where you are meant to be self-supporting and audacious and challenge yourself, and which is undertaken by people who are
ded 'ard and who will do things like carrying on riding when their frame breaks in two.
This is FNRttCing, where you are meant to have fun and get there in time for (beer for) breakfast and allowed to be useless at fixing punctures and minor bike wibbles, although people might
take the piss laugh and point in a well-natured lightly mocking jovial manner while they help you.
It'll fit in a jersey pocket. But I think it'll just annoy me there.
