The Time Machine

Minimum participants 6 to 10 people (varies per competition)
How does it work The more you are, the more the price goes back. Even if you register close to the race, you can pay the price of the first bracket.
Example 12 people, Sardon Half Marathon 22 km, last price tier (€ 45). With the Time Machine → first tier: € 35 each. I'm saving €120 on the group.
