Barrel 100

Multirun, fixed 100 km total, as many sessions as needed within the window. Scoring follows the mechanic—best total time on the distance once work is verified (detail in the Rulebook).

Clock (UTC). The live window runs UTC, from 00:00 on 1 April through 23:59 on 30 April. Only activity published to Barrel 100 inside that span counts; how the kilometres split across days is a scheduling problem for the entrant, within format and verification rules.

After the window. 30 April closes the live phase; official standings follow later. A gap of a few days before Results out is normal; busy or contested fields can take longer while verification clears. The Rulebook maps Under review → Results out; here the only takeaway is that provisional order can move until the race is Results out.

Why “Barrel”. When barrels move, markets react. Barrel 100 keeps the idea simple: the number runs.

A hundred kilometres spread with discipline: legs, recovery, sessions that pass verification. The Multirun shape rewards planning—whether the hundred is stacked across many easy days or forced through fewer long ones.

April itself is part of the load: weather swings, travel, ordinary life between runs. The race does not wait for perfect conditions.

• Front-load vs back-load — Bank distance early and live with tired legs later in the month, or hold back and compress the hundred toward the end with a thinner error margin.
• Steady vs volatile — Even slices across the window vs clumped blocks; each pattern trades risk of interruption against risk of fatigue.
• Enter vs stay out — Full commitment to the hundred and its proof burden, or no entry; there is no partial score for hovering at the door.

A verified 100 km block is visible on the leaderboard: it separates entrants who cleared the distance from those who did not. Late entry mid-month can still finish in time if the hundred fits inside April as counted UTC—the window is long, but not infinite.

At Results out, this race locks into the record; until then, provisional standings are allowed to shift.
