''Rasputitsa'' ( rus, распу́тица, p=rɐsˈputʲɪtsə) is a season of the year when travel on unpaved roads or across country becomes difficult, owing to muddy conditions from rain or melting snow.
Etymology
In Russia, the term , рас- (ras-), disagreeable, + путь (put), travel, + -ица (-ica) refers to the spring or fall, and also refers to road conditions during such a period.
The Ukrainian equivalent () usually refers to springtime but rarely autumn, when rain and/or melting snow on unpaved roads, tracks, paths, or any poorly-drained off-road area turns the route into impassable deep mud.
Similar terms are Swedish ("bad going"), and Finnish ("broken state of roads"), but both also apply to when water is too iced over for boats but not strong enough to cross on foot or in other vehicles. Finnish eastern dialects also have a loanword (), which is used in the same meaning as .
Effects

The term is applied to muddy road conditions in Belarus, Russia, and Ukraine, which are caused by the poor drainage of underlying clay-laden soils found in the region. Roads are subject to weight limitations and closures during the period in certain districts of Russia. The phenomenon was a hindrance in the early 20th century in the Soviet Union since 40% of rural villages were not served by paved roads.

Prior to the 2022 Russian invasion of Ukraine, some analysts identified the logistical challenges of the mud season as a likely hindrance to any large-scale invasion in spring. When Russia crossed the border, many of its mobile units found themselves stranded in fields and limited to major roads, where resistance and logistical issues significantly slowed the advance toward Kyiv and elsewhere.
