Quasar

Multirun, fixed 50 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 1 October through 23:59 on 31 October. Only runs published to Quasar in that span count; how the fifty kilometres split across days is up to the entrant, within format and verification rules.

After the period ends. 31 October 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.

Fifty kilometres across the whole of October: a full-month fifty, more room than Sun’s thirty in September, still a distance that disappears if the first two weeks stay empty. Split it evenly or in fewer, longer runs — the dates do not wait for a late start to become a plan.

October is already stacked when this race opens. Guadalajara (Open) starts the same day and runs into mid-November — not a day-one entry. Vermeer opens on the eighth (Classic, 10 km). Delta on the tenth: Distance Ladder, 100 km, through 20 December. Scary Run occupies the last week of October. Groza sits under the whole quarter and does not close calendar gaps.

• Early vs late — Clear the fifty while October is still wide, or compress toward month-end and accept a thinner recovery lane if something slips. Sparta opens the day after this race closes.

• Many short runs vs fewer long ones — Tracking friction and fatigue trade against flexibility. Fifty kilometres in a month is easy to underestimate.

• Enter vs stay out — A defined 50 km with proof, or no line on this race. It is the Cosmic collection’s October mark on the board; skipping it is a choice that registers.

A completed 50 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 31 October UTC.

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