Singapore Marathon 2016 run by heart rate
We took the children to run the Kids Dash the evening before the race. We were a bit delayed in starting and it was very, very crowded, but the kids seemed to enjoy themselves. My eldest son asked to borrow my watch to time himself over the distance - he ran hard the whole way and finished third or fourth in his wave. My middle son ran as fast as he could with Dad and was very chatty and super proud of his finisher medal at the end.
