The Cambridge Half Marathon was held on 3 March 2019. There were ten thousand runners and many of them were raising money for charities. Amongst them were two runners from Bishops Stortford Running Club, who ran for the British Thyroid Foundation. Despite the drizzle both Peijie and Serena thoroughly enjoyed the flat and scenic course, which took them past many of the Cambridge University Colleges and historical landmarks.

Peijie and Serena raised £180 for the BTF.
