There's always the option of buying DIY/Perm cards in bulk and validating that way...
I don’t use Strava can I still take part? Unfortunately this makes it
difficult for us to track you. If you would like to use homemade
checking cards just as they did in 1911 or send us copies of ,or links
to, completed Audax verification then that could work.
I think Steve A will have me well and truly beat so I don't actually see much point but it's another little thing that might get me out when I otherwise would've stayed at home sinking beers.
