Does my team have to have 4 members?

Yes. You can only participate in Coastrek as teams of four. If you need to recruit additional members, maybe try:

• Our team vacancies page - at www.coastrek.com.au, select your event and choose 'Team Vacancies'
• Here are some places to find teammates you might not have thought of! 
  • Post in local bushwalking, running or hiking groups on Facebook.
  • Post in local mums groups on Facebook.
  • Ask your gym or yoga studio if you can put a callout on their noticeboard.
  • Ask your workplace if you can put a callout on their noticeboard or intranet.
  • Ask your book club or kids sports team group chat
  • Ask an old friend you haven’t seen in a while
  • Ask your parents or kids (over 16s)

If you only have 1 extra, find three more friends and enter two teams, or train as a team and have the extra person as a reserve. Don't forget that Support Crew often contributes to the team just as much as the 4 trekkers!
