The day has come! 

PhD athlete Ross Edgley set off at 7am on Thursday 13th July to take on the colossal challenge of the world’s longest lake swim. He is attempting to swim over 170km (106 miles), in order to beat the current record of 168.3km. This isn’t Ross’ first rodeo, his first challenge, in November in Loch Ness, Scotland, was stopped due to Ross developing cellulitis and hyperthermia. Ross was pulled out at 53 hours, having covered 79km. Since then, Ross has re-strategised and ensured that all the lessons learnt from Loch Ness have been addressed. 

With a new (and much warmer) location, Lake Trasimeno in Italy, no wetsuit and a leaner, meaner physique we’ve been working closely with Ross and documenting the journey to this swim. 

You can get yourself up to date on all the episodes here.

The rules of the world record attempt are as follows; no rest or sleep, no wet suit, no flotation devices and no touching the boat or land. 

Check out how Ross is progressing below.


UPDATE 13/06/23 10:06am

Starting with a healthy 3km per hour pace, Ross is 3 hours and 9km in and has set into a bit of a rhythm. Leading up to the swim, Ross mentions he refrained on all things caffeine to keep his dopamine levels low. As we approach the evening, he is looking forward to his first sip of PhD Charge pre-work-out to really get the gears going!  

As we progress throughout the day, Ross started to experience cramping in his calves, just 4 hours in this isn’t what the crew had wanted. As they started to address this as per the protocols, hours passed and Ross’s symptoms were worsening. The day before the swim Ross was experiencing some oedema (excess fluid) in his calves and the medical team were worried this was progressing throughout his body. After consulting experts and further assessing the situation the crew were relieved to pass this as cramping and Ross managed to shake it off as the crew picked up moral.  


UPDATE 13/06/23 14:00pm 

At 7 hours in and we reach 20k. A healthy pace as Ross starts to shake off the cramp and really charges his way into a rhythm. Contrarily to the freezing temperatures of Loch Ness, the water temperature in Italy reaches 28 degrees, this of course brings its own challenges as the forecast is due to get warmer at Lake Tresimeno. As the day draws to a close, we are 16 hours in and 37 kilometres down, pacing at 2.34km/h we head into the first overnight swim.
