18 April brings thirty-six runs from thirty-one athletes, about 408 km. The headline in the raw numbers is structural: Nairobi accounts for 170.7 km across eleven sessions, while Barrel 100 logs 153.4 km across fifteen. Barrel still leads on session count, but Nairobi now carries more raw daily distance. That inversion has not happened before in this season’s scout record. It is a consequence of what has been building since day seventeen: more athletes have closed their Barrel slots and are pointing output elsewhere, and those who remain on Nairobi are running longer individual sessions as the open-distance ledger compounds.
The single number that explains the Nairobi kilometre total is Vyacheslav Krymsky: 64.1 km published to Nairobi in one verified outing. Before this session, his cumulative total on the open race sat near 119 km; the temp board now places him at 183.1 km, second among men. Vladislav Kokorin still leads men at 197.4 km – a gap that was around 78 km before the day opened and now sits at about 14 km. Krymsky has not overtaken first place, but one session compressed a gap that looked stable for most of the past week. How much of that margin survives depends on whether Kokorin responds in kind or whether his output stays at the rolling fifteen-kilometre pace he has been running on Nairobi since the season opened. Nairobi does not lock at a target distance, so both totals will keep shifting; what the 18 April slice records is that the men’s Nairobi contest is no longer resolved by a comfortable cushion.
On Barrel 100, nine men now sit above the hundred-kilometre target on the temp board – all carrying completion percentages between 100.1% and 111.5%—alongside four women. The remaining Barrel contest is among the women still short of the target. Tatyana Sesina is the clearest case: 15.3 km published today, bringing her to 81.8% on the temp board with around twelve days remaining in the April window. The arithmetic is accessible – roughly 18 km still needed—but the time cost of each additional session is shared with Diego Velázquez, which closes on 22 April. Sesina also posts 5 km on the Art multirun in this slice. That kind of day—splitting output between two active deadlines—describes the exact constraint the end of April creates.
The fourth woman to clear Barrel is Gulnaz Gaynetdinova. Two sessions in this batch: 19.8 km and 13.6 km, totalling 33.4 km published to the hundred. She lands at 100.6% on the temp board. Unlike the front women who finished Barrel early and have been feeding Nairobi and Velázquez for days, Gaynetdinova finishes later in the month, which means her open calendar starts now rather than a week ago. Her Nairobi total is visible but not yet near the top of the women’s table; how much she can build in the remaining eleven weeks of the City race will partly depend on how much April exhausted her.
Elizaveta Troshkova, who cleared Barrel on the first pass and now leads women on Nairobi at 162.3 km, adds 10.5 km to Nairobi in this slice. The session is not exceptional in volume – it is maintenance of an open ledger that she has been feeding steadily since late week one. Troshkova also has a completed Velázquez line. At this point in the season her position has the shape of someone who resolved each fixed deadline early enough to keep Nairobi running uninterrupted.
Diego Velázquez takes nine sessions in the batch, 63.6 km. Seven men and ten women already show completion percentages above 100% on the Art temp board; the remaining entrants have four days before the window closes. Nikolay Simon posts the longest Velázquez line today at 16.7 km, Dmitriy Bulatov adds 12.1 km. The Art race is finishing on schedule and will leave the calendar once April closes, thinning the active format list for the first time since season start.
Mistake registers a single session: Ilya Muzurov at 20.4 km, placing him at 40.8% on the pace-locked race. Muzurov already holds a completed Barrel slot, so his Mistake work sits alongside Nairobi credit rather than competing with an active multirun countdown. The rest of the field active in this scout batch does not overlap with Mistake, continuing the pattern from the past several days where pace-locked entries belong to a narrow subset of the total active roster.
The thread from earlier in the season still organises the picture. April’s multirun dominated session counts through week two; now, with most Barrel leaders past their ceiling and Velázquez four days from close, the daily balance tips toward Nairobi for the first time. That shift is not soft. Krymsky’s Nairobi outing is the largest single-race distance posted by any athlete in any daily slice this month. Whether it holds as an outlier or signals that more entrants will push Nairobi volume hard as April frees up remains the open question going into day twenty.
