Given that some of the descents to come were steep and fast, this was not a good thing.
A quick inspection which revealed no obvious holes and only a light hissing sound, I opted to pump the tyre up by hand, spin it quickly to distribute the sealant, and keep going.
I stopped again probably half a kilometre further on to top up as the tyre was still a bit soft and squirmy, but couldn't hear the hissing so I pressed on again after adding some more air. Tyre stayed up for the remainder of the trail with no further loss of pressure.
Modern mountan bike technology is cool
