You can tick away to your hearts content on here
https://www.hill-bagging.co.uk/ The only thing is that you will have to get your head round the difference between Marilyns, Tumps, Humps and all the other things people bag there from Trig points to the miscellany the O/S left behind while making the maps to SIBs (Significent islands of Britain) and Siblets. There is also a facebook page for addicts. I thought I had done well on the Marilyns (Sub2000s) but Boy oh Boy ( and most are boys), when it comes to bagging I am still in nursery school. One guy would go after the Ultras if so many weren't on war zones.
