I agree with Marie and PaulK... the club would benefit from promoting a similar mid-week outdoor trips challenge with 3 or more participants.

Agree with Marie. We need a 6-3-6 mid-week challenge!

Really cool idea :)

I've got a comment though:

I don't agree with the "minimum of 6 participants" because:

1/ Some people like huge groups and that is cool. But others prefer small groups of 3 to 5 participants. For more challenging objectives, such small groups might be better. It also makes it easier not to lose people in the woods and really move as one group rather than a series of little sub-groups with potentially poor communication between them. It also helps to have a more homogeneous group in terms of speed and level and it is safer when conditions are touchy

2/ Some people post mid-week trips and those bring lots to the club as well. But mid-week organizers are penalized in this challenge since few people can join mid-week trips

So this is a cool incentive, but it encourages large weekend groups which is only one type of BCMC trips. But maybe this is the type of trips that the BCMC wants to see?

Great picture!
