TBH having done cheap and not so cheap events like brother in the wild and more expensive events like the gravel dash I can see the benefits of both. price difference between the two was pretty big, overall cost at the end once I'd bought food ended up being about the same.
Having spoken to people who've organised events like these, they really aren't done for the money.
And come on, it's not exactly pannier.cc prices.
Don't like it don't go. simples.
If this wasn't the same weekend as the gravel dash I'd probably go, and as the gravel dash is now sold out this seems a good option and good luck with it!
