Yeah ... as it's just a bit of fun I may head off with my own slightly weird challenge with its own rules - one of which will be "no one else is allowed to enter".Hmm, that would make things 'somewhat difficult'...
The challenges are only a bit of motivational fun anyway and these are exceptional circumstances, so let's just call this a special year which (hopefully!) won't be repeated and do whatever we can, however we can?
Come to think of it, another will be "the rules are secret".
I may let you know if I succeed.
