Boswell is determined to hang onto his podium place but admits he doesn’t know what to expect from tomorrow’s time trial.
"I haven’t done a time trial this season!” he laughed. "So we’ll see. I’ve been training on my TT bike a bit more in anticipation for this event, but I’ve missed two key opportunities to get in some time trial practise at the Volta ao Algarve and Tour de Romandie because I’d pulled out.
"Then, in this event in 2014, I was messing about a little in the time trial warm up and Dave Brailsford said, ‘You better get dialled, because one day you’ll need to do a good time trial!’ And now that day has arrived! I wish I’d listened.
"But of course I’ve done time trials before and I’ve been on my TT bike more this year, so it’s definitely improved.”
Yet whatever happens around Big Bear, the 26 year old revealed that he's happy with his week's work in his homeland.
"If the race were to finish now I’d be third on GC, which I’d say is really successful. It’s been really enjoyable as well - mentally it’s been relatively relaxing and fun to race on somewhat home roads, have my family here, and see friends on the side of the road. I’ve really enjoyed the whole race."
