Well done!

Never completed it; never likely to :)

A year. I did one red trail many years ago then started back with them March last year, after finishing Alice and completed them in March this year. Should have done them the other way around in hindsight but never mind 😃 The GH is worth it.

1 year 4 months approx., with a few mini breaks in between.  As Lesley states, the GH is so worth it.  It has changed the whole dynamics of the game for me x

About a year for me too

I did mine in just very slightly under a year. Started in January and finished in December, I remember vividly being desperate to finish so that I had time to do the advent calendar. Haha.
I didn't take any breaks to do anything else and always had 2-3 trails on the go at the same time.
