The only way to guarantee yourself the same starting battery as your friends is to create a team. You can create the team during the registration process to allow your friends to take part in it, or you can join an existing team.
If the battery is full and you are left out of your team battery contact the organizers at the following address: italia@spartanraceeurope.com
Entries in the Elite battery can be entered in a team, but will not be moved from the selected battery. No refunds will be given for those registered in the batteries with surcharge (Elite and Age Group), who decide to change their starting battery. Requests to change battery will be accepted subject to availability of places. Athletes registered as individuals may request to be included in a team by contacting customer service no later than 14 days before the event.
