This is reflected in what was an extraordinary 12-month period for Israeli track and road running last year. 2019 brought 13 new national records, six of them set by Lonah Chemtai Salpeter, whose achievements included breaking Paula Radcliffe’s 16-year European 10K record.

Felsenstein’s own sporting career has spanned Hasmonean school, Shaftesbury Barnet Harriers, the London marathon, and the 1981 Maccabiah where he ran the half marathon, 10,000m and 5,000m, “all in one week and in that order.” A key influence in his early competitive years was Harriers’ Bryan Smith, whose wife Joyce won the first two London marathons in 1981 and 1982 and who still coaches V55 300m and 400m sprinter Colette Hurley. 

Felsenstein made aliyah in 1982 and almost four decades later he is, at 62, still an active endurance runner, although these days he limits himself to the 5K and 10K distances. “I’ve got some competition,” he says, “but I’m in the top three in the 60 to 70 age group.” 

The masters athletics scene in Israel is very different from that in the UK, observes Felsenstein. “No vets do track and field and there are no dedicated vets leagues. It’s mostly road running, usually split into age categories.”

Felsenstein belongs to a team made up of colleagues from the Hebrew University of Jerusalem, where he is chair of the Department of Geography. “I train with the Dean of Social Sciences,” he says, ”and the head of the Hebrew University Business School is one of my closest rivals. Each year brings a reassessment of expectations.

“My aim is no longer to improve on what I did the previous year but to decline at a less rapid rate. I’m just happy to run, be fit and not be injured, especially having come through cancer six years ago.”
