I passed the 21K marker at about 1:53:00, a pace of 5:23/K (8:40/M).
I had been debating all week whether to play it safe and run at
a 6:00/K (9:39/M) pace, the same as I had been training at, or to
go for it and try to maintain around a 5:30/K (8:51/M) pace. Obviously
I elected to do the latter, and was even surpassing this.
The route followed a very pleasant bike path along the Alb, a small
local river that flows through Karlsruhe. The sun continued to shine,
the skies were blue, but oh so cold!
