Multirun, fixed 30 km total, as many runs as needed inside the dates. Scoring follows the mechanic — best total time on the distance once work is verified (detail in the Rulebook).

Clock (UTC). The race is open UTC from 00:00 on 5 September through 23:59 on 30 September. Only runs published to Sun in that span count; how the thirty kilometres split across days is up to the entrant, within format and verification rules.

After the period ends. 30 September 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.

Thirty kilometres from the fifth to the last day of September: more room than a two-week Art multirun, less than a full-month fifty. The kilometres still divide however you prefer — steady accumulation or fewer, longer runs — but the dates do not wait for a slow start to become a plan.

September is already in motion when this race opens: Harvest has been live since the first, Thirteen until the fifteenth, Hyperdrive 50 until the twentieth. Cézanne opens on the eighth; Petrov-Vodkin on the tenth. The thirty kilometres land inside that stack, not on an empty field.

• Early vs late — Clear the distance while the dates are still wide, or push volume toward month-end and accept a thinner recovery lane if something slips.

• Many short runs vs fewer long ones — Tracking friction and fatigue trade against flexibility.

• Enter vs stay out — A defined 30 km with proof, or no line on this race. It is the first Cosmic collection mark on the board; skipping it is a choice that registers.

A completed 30 km multirun 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 30 September UTC.

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