Wanders has been in fine form of late. In 2017, he set pbs at 1500 (3:44), 5000 (13:37), 10,000 (28:06 - same as Wejo) and on 13.1 (61:43). Then he really got it going on the roads at the end of the year, running 22:46 for an 8k win in November, then 28:02 for a December 31st win at the Corrida Pedestre Internationale de Houilles 10 km and now the big half marathon pb (previous pb was 61:43).
Last night, we got an email from the operators of a swiss track website who noted that some posters said there was a lack of English documentation on Wanders - so they went and subtitled in English a video about his life in Kenya. Fantastic stuff.
