The registration price includes access to your chosen challenge/race in the Pacer App, the digital E-certificate, and the real finisher medal.
Notice that tax and shipping are not included in the registration price, and are calculated at checkout.
You don’t need to upgrade to Pacer Premium membership. The registration code you receive upon checkout already grants you access to the challenge/race.
You are welcome to try the Premium membership. It unlocks many interesting features, such as training courses, fitness plans, advanced analytics, and more. When opening the Pacer app for the first time, you may be prompted with an "Upgrade to Premium" screen. You can dismiss or skip that screen, and go on with your registered challenge/race without a problem.
