‘Triathlete’ Paul Hart has his 50-mile record smashed!

Faster and faster. The ever-increasing speeds we are seeing on the UK time-trial scene continued on Sunday - which meant that former triathlete, Paul Hart, lost his 50-mile Competition Record to a staggering ride from Marcin Bialoblocki

Domestic Time Trial racing continues to get faster and faster

In May this year (HERE), I highlighted how Paul Hart – a former British Age-Group duathlete and ETU medallist – had broken the Competition record for 50-mile TT, recording a time of 1:34:37, to slice six seconds from the previous best of Matthew Bottrill.

Well, that time was yesterday – in time trial terms – put into a different time zone with the performance of UK-based Polish athlete, Marcin Bialoblocki, who on the same E2/50C course near Newmarket clocked a staggering time of 1:30:31 (that’s 33.143 mph average!), in the Shaftesbury CC open event. His 25-miles splits were incredible; 45:13 followed by a 45:18.

You can check out his ride on Strava HERE.

Marcin is a time trial specialist and was recently second in the Polish National Championships to Maciej Bodnar of the Bora-Hansgrohe Pro Cycling Team. Given that Maciej finished sixth in the 2016 Olympic Time Trial (ahead of current Tour de France leader, Geraint Thomas), finishing just 17 seconds behind him gives some measure of the ability of Bialoblocki, who continues to push forward barriers on the U.K. time trial scene. Take a look at some of his recent records for evidence of that…

Marcin Bialoblocki Competition records:

  • 10 Miles – 16:35
  • 25 Miles – 42:58
  • 50 Miles – 1:30:31
