Slow out, fast home
Ten of us went to Greenwich tonight taking it gently on the way and then splitting into two groups of five for the return leg. We in the 'fast' group kept a good pace and the return took about 25 minutes compared to 50 minutes on the way out (mainly due to having the tide with us).
There was a lot of traffic and we encountered some quite choppy conditions on the way back in Limehouse Reach as two fast ferries passed at the same time in opposite directions.
