The start the next day was scheduled from the town of Mojkovac to the Biogradska Gora national park. The town was supposed to be quite small, 4k residents according to Wikipedia. Hopes of finding a new rim for Andrey to replace his bent one, and a spare tire for me, were rapidly melting away. I wasn't as anxious yet — Doomer mentioned that a 26-inch inner tube could be stretched onto a 28-inch rim, something he had seen Alexey, widely known in narrow cyclist circles, pull off.
I tried it — and, oh miracle — the trick worked. So it was only Andrey whose knees kept shaking.
