2 weeks isn’t long enough, can’t you get them to agree to 3 months ?
I had a stint of 3 months back in 2006 whilst a re-org was in flight, I had to go into the office once every 2 weeks and had conf-calls every week for an hour with my Director.. we spoke about golf because he was in exactly the same position as me, I hate golf – those hour long conversations felt like a week. So, I filled my weeks up with sailing, I got a training plan organised, set an intermediate goal of top ten in the Nationals, I came 11th. But it does show what can be achieved by focus and training.
2 weeks isn’t really enough, once you’ve changed the bed linen and ran the hoover around, filled the dishwasher and been to the pub the times gone.
Plan a few long distance rides with an over night stop, something you’d never really do in “real life” take yourself out of your comfort zone.
