Set out on Saturday to cycle home from Cambridge. Expected to follow the Welwyn train line and figured I’d run out of beans by Potters Bar. Unfortunately I drifted a bit east and ended up having a massive climb 1/3 of the way in.

Didn’t notice anything unusual at the time but really started flagging well before mile twenty. Also, wore the wrong shorts so crotch on fire fairly quickly. In the end I passed under the A10 and started down to ware as light began to fade.

Plan to try this again asap but with better shorts and taking the north/south route closer to Royston. Also, really need to get an earlier start!
