How to start a relay for life team
Ask about 15 close friends or family members if they are interested.
If they are, write down their names, and ask for team name ideas and possible fundraising methods.
Hold a team meeting.
It doesn't have to be formal; meet at your house or at a local coffee shop or somewhere similar. If you can, bring a laptop so your future team can be there when you sign them up.
