Fundraising tips and FAQs

Fundraising tips

The easiest way to collect donations is to set up an online fundraising page on JustGiving. This can be shared easily with friends, family and colleagues – you’ll be amazed by how generous people can be.  

To boost your fundraising, why not organise some additional activities to run alongside your Tennis-a-thon challenge? This can help you smash your fundraising goals.  

Here are some ideas:  

  • arrange a raffle – we have a letter of authority that you can print out and take to local businesses to source prizes. Please email and we can send this to you
  • hold a sweepstake: you could ask people to guess how long your Tennis-a-thon will take, or the number of steps you’ll take on the court during your challenge 
  • organise a bake sale or summer barbecue at your event to bring in some extra donations on the day 
  • run a tennis tournament for a donation on entry: you can download and print the promotional poster to spread the word
