  • Did the 10K in 2019

    Very slow start for a mass race. Released in twos and that took over 25 minutes to cross the line. Course was very narrow and dangerous to pass. Style at the turn point was crowded and had to wait to go over causing me to cool down. Some of the downward paths were steep with sharp turns miss a turn and you could end in the river! Tunnel was poorly lit and very uneven again dangerous. Only good point was the medal for the finish. Never doing again!
