Ideas for fund-raising challenge my work can do

[Firesidefox]

My boss has asked me to have some ideas for a fun, charitable challenge we could do that people from work could join in to raise money for charity.

He really likes the idea of kayaking down the Thames over five days, but has asked me to come up with others.

Must NOT involve mountains, swimming or running (he and other senior bods have health issues that mean these wouldn't work).

I am stuck and don't know where to look for inspo - has anyone got any good ideas?

Dunno but please tell your boss I am very happy to not work for him. Are those 5 days on top of annual leave?

I'd do small anonymous things that didn't show people up for what they can or cannot do.

Need more info. Why are you doing it, what charity, why that charity, how much you hoping to raise, is work giving people time off to do it, will work pay for the activity, is it a joint thing or are people doing it individually. Does it tie to a national fundraising effort
