Made it around Lake Harriet in a death defying 22:16 unofficially. Splits at 1M - 6:58 at 2M - 7:26. The ham was OK until about the 2K where it started to be a bit bothersome. So I backed off and was happy to finish. Yeah it was very very very slow. But at least I did not blow the ham completely.
Ice awaits most certainly. I may bike later today to keep everything loose. We'll see.
