In the last 3000 miles I estimate I walked 300 miles in company.
That was with a church group on the WHW this summer, a couple of days on the TGO challenge in 2018 and taking my kids up Ronas Hill and visiting a few Brochs in Shetland.
The rest of my walks are solo.
I don't mind the company, but I see so much more when going solo. Especially wild life. Otters, birds, seals etc.
I tend to look at group walking as a different experience than solo walking. a bit like hill and coastal walking as a different experience to road and Down walking. Or when I used to run as cross country running to track running.
