Nebulus

Running around a giant square shaped road circuit. Must be a few miles on each side. There is change link fence on the inside and the pavement is white and mostly free of people, except those couple running with me.
It takes so long to get round that it is now noon and the weather has changed to full sun, making me feel exhaust and strip off my jacket. It is one long slog.

note: tried wbtb several times after
