The best way to get all the information you need prior to an event is to head over to your race's event page.
Go to www.spartan-race.cz and find your event on the timeline in the middle of the page.
On the specific event page, you'll see a section for "Important Race Documents". As the race gets closer, we'll add all sorts of downloadable files that will have the information that you need. Typically, these files are available the week of the race.
You will find there Waiver and Start List usually from day one when registration is open. This Start List do not include BIBs, and its purpose is just to check if registration gone well. Official BIBs will be add last Wednesday before event. Also Athlete guide will be publish here minimum one month before event. Last week before event will be visible list of Trifecta qualifiers. The Course Map will be published right after event.
It's a good practice to visit your race's event page often, as it will always have the most current info about your upcoming race. That includes the following details: the location of the event, where to park and pick up your registration packet, as well as hotel and Workout Tour updates, special charities or features of the race, etc.
