Singularity

Distance Lock, race distance 30 km. Each published run must fall in the 5–6 km corridor. As many runs as needed to close the thirty. Scoring follows the mechanic (detail in the Rulebook).

Clock (UTC). The race is open UTC from 00:00 on 15 December through 23:59 on 31 December. Only runs published to Singularity in that span count.

After the period ends. 31 December closes the live phase; official standings follow later. A gap of a few days before Results out is normal; heavier fields can take longer while verification clears. Provisional order can move until the race is Results out.

Sixteen days in late December to close 30 km, and every counted run is 5–6 km. Shorter or longer than that band does not count.

December is already loaded when this race opens. Lisbon (100 km Multirun) stays open through the 31st. Kandinsky (Classic, 10 km) runs until the 21st. Delta (Distance Ladder, 100 km) closes on the 20th. Groza covers the whole quarter and does not close calendar gaps.

• Enter vs stay out — Close a locked 30 km in the Cosmic series, or leave December without this line.

• How to stack the thirty — Stay near 5 km or near 6 km; that choice sets how many runs the distance takes.

• When to start — Early in the period, or toward 31 December with less room if something slips. Lisbon and Groza are still live.

A completed 30 km lock is a clean line: finished or not, inside the UTC dates or not. Late entry still works if the kilometres fit before 23:59 on 31 December UTC.

At Results out, the race locks; until then, provisional standings may still move.
