When I fundraised, I...
Made sure I had support from the charity. That came in the form of publicity (I did radio interviews and all sorts!), promo materials (collection tins, balloons, t-shirts etc). This came with support from their own supporters too.
Contacted all manner of local companies and attractions who donated hugely generous things - vouchers, tickets, bottles of wine, chocolates, electrical items, so many generous donations. I used these for raffle prizes at other events, see below!
Events:
I had support from my employer (and by default their client base!) and was able to use their premises to hold a Christmas craft sale. I gave local crafters a stall at the venue in return for a donation to my fundraising. I also included a cake sale (my colleagues generously baked too!), tea/coffee for a small donation and held a raffle here. Tesco very kindly donated tea, coffee, milk, disposable cups etc. for this too.
Bingo night - my husband was the bingo caller, the cricket club we held it at had a PA system and gave us the venue for free in return for people buying drinks there. Also held a raffle here as well as other prizes.
And then social media
I created a Facebook page to share my training. The good, the bad and the (sometimes very!) ugly. Pictures (especially in charity t-shirt!), progress, successes and failures. I was and still am not, and never will be a runner so it was pretty brutal! Updates were posted at strategic times to maximise engagement. I was very open about my own journey (I'd been super morbidly obese beforehand!) and also about the work the charity do and how they support the local community. It was also featured in things like whole organisation newsletters etc. At work.
Marathon day I wasn't aiming for a specific time, I was just aiming to finish and still be alive. So I had some fun with that too and did a photo scavenger hunt. People pledged donations for certain things e.g. a picture of someone running with a fridge, or a selfie with a celebrity etc. which was actually really fun and quite popular too.
It was hard work, and about 30% of my donations came in on the day or after, but it kept me going on the day. When I was struggling (Isle of Dogs, fucking he'll...) I mentally calculated how much each mile was worth based on donations and it really kept me moving.
Hugely humbled by the amount of support I received all round but you'd never get me to do it again, truly a once in a lifetime experience 😂
