Came across an article from 2013 listing where the best places are to win free climbing and outdoor gear (who doesn't love free stuff after all?), and wanted to make an updated thread of the ones that I knew about, and see if there is any that I've missed!
1) UKC
The obvious, UKC run a few competitions a month for gear in the 'Competitions' section of the website, they're usually open for a few weeks and seem quite popular, with at least a thousand entries on most of them!
2) Ellis Brigham
Sometimes offer gear and trips for climbing and adventure sports. Seems a bit sporadic and there is only a new compeition every few months or so.
3) Win Something
Generic competitions site, rarely offers adventure gear under the 'hobbies' section of their website, but seems to be updated fairly often.
4) Snow + Rock
Runs a couple of competitions a year, mostly photography related, but their website hasnt updated recently.
5) Walk Magazine
Hosted on the Ramblers Website, they mostly offer walking related gear in what seems like semi-regular competitions every few months.
6) Summit Magazine
The BMC magazine published quarterley always has a section for competitions with both walking and climbing gear offered. Requires a BMC membership though.
7) climbers.crag - Instagram
Climbing page on instagram offering competitions for gear every month or so, usually involves sharing the post and commenting on it to boost the page's publicity.
Is there any I've missed?
