Supernova

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 15 February through 23:59 on 31 March. Only runs published to Supernova 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 March 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 from 15 February to 31 March: more room than Moon’s forty in February, 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.

February is already stacked when this race opens. Moon (40 km Multirun) stays open through the 28th. Rome (Distance Lock, 50 km, runs of 5–10 km) closes on the 15th — last day overlap. Osaka (120 km Multirun) runs until 10 March. New Orleans (Classic, 11 km) opens on 1 March. Unfrozen covers the whole quarter and does not close calendar gaps.

• Early vs late — Clear the fifty while the dates are still wide, or compress toward March and accept a thinner recovery lane if something slips. New Orleans opens on 1 March.

• Many short runs vs fewer long ones — Tracking friction and fatigue trade against flexibility. Fifty kilometres across six weeks is easy to underestimate.

• Enter vs stay out — A defined 50 km with proof, or no line on this race. 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 March UTC.

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