More marshaling

It was cold, it was wet, they needed more marshals...

I ended up doing some fast L4/L5 intervals after I got home in the afternoon. Only to get rained on anyway. By then it wasn't quite as cold though.

Did 10x3 L4, target 350-400 AP, with about 2-3 minutes rest between each. This is 700m at 9%, then, circle around back to the bottom and redo.

Almost but not quite an NP buster ride (1.04 IF, > 1.05 is NP Buster.)
