And the world record 65+ 5 k 16:36:59 by Alastair Walker at age 66 is still not beaten....😁🏃
The " requirement" to beat it looks simply like this training ; Running 20 x 400m @ 78-79 sec with roughly 60 sec easy walkrest, running LT2 threashold intervals around 3:35 min / km and easy steady runs at around 4:45 min/ km. Looks not impossible on paper ,does it? Well, really tough to an aged 66 fellow , but as said not impossible. 🏃🧙♂️
