Clare said: 'It hurt all the way, I have never pushed quite that much yet this year but it was by far the most enjoyable event that we have done so far! I loved every minute'.
Liz was very pleased with her personal best time but is still really keen to get under the 1 hour time.
She said: 'I was so close to a sub 1 hour 10k – I can't wait until our next one to prove to myself I can do it!'
