Another incredible ultra-runner from Lithuania is Aidas Ardzijauskas who last year completed his 444 day run covering 30303 km, which is on average 68km every day for almost 1.5 years! His plan originally was to run around the world, but during the pandemic it wasn't possible to do that so he just ran it all in Lithuania. Unfortunately there isn't much English-language coverage about the monumental feat, but this is readable with Google translate:

I've attended Computer Architecture lectures with David May - incredible character with profound knowledge of anything related to computer hardware.
His new company (http://xmos.com) is also worth looking at if you're interested in parallel computing.
And he tracked everything on Strava too - https://www.strava.com/athletes/16416410
