Seems there's a move towards more Saturday events which makes competing difficult for me for one. Is Sunday becoming a day of rest? Sundays are much easier for me. Anybody else have views on Sat vs Sun?

I find Saturday is easier for me. My other half always seems to think of jobs I really have to do on Sundays while she can usually entertain herself on Saturdays and doesn't notice my absence. It's not too bad for local events when I'm back by lunchtime but more distant or longer events are a problem on Sundays

I think the move in MTBO is generally due to the amount of Foot-O/XC events on Sundays. Most Orienteers wouldn't give up their Sunday Forest sesh, so Saturdays tend to encourage more people to turn up to events. The Southern MBO Series decided to put the vast majority of its events on Saturdays simply because often the Orienteering clubs are organising other races the next day - and we've noticed a vast difference in the numbers competing!

I can't speak for trailquests etc.!

Just another thought to add............from an organisers point of view I find Sundays better as it gives you Saturday to put the controls out.

As Emily says, Sunday is for orienteering.
I certainly wouldn't have started riding in MBO if events had been on Sundays.

Historically NYMBO was part of EBOR (orienteering club), so their events have traditionally been on a Saturday. This year most NEMBOS events are Saturday, and so are a lot of winter series events. But I think XCC, DandW, Scotland and the now defunct Epic have most of their events on Sundays.

So it depends a bit on where you live. I think the more variety the better.
It ultimately rests on organisers to fix their dates to attract the riders they hope will compete.

Personally, I can't think of a better w/e than MBO on Sat and orienteering on Sunday, and orienteering will improve your navigation skills!
