GPS coordinates of the buoys were accurately recorded through handheld GPS, so as to avoid any erratic measure of watch GPS. Pictures with GPS coordinates at the points of placing of both buoys are provided, and so is the measured distance between the 2 GPS-identified points.
The course was near the shore of the lake, with distances from the shore ranging from 5 to 20 metres. Support and safety were ensured by a kayaker and a SUP
Water temperature was taken in the area between the 2 buoys, with displays laying on the SUP surface and the probes placed at some 20-30cm beneath the water surface. The picture that displays the thermometers, was taken at 12.43. The swim started at 13.03
Before the swim, a briefing paper was read by the Observer, notifying the swimmer of the rules, and instructing the organising team about individual roles, safety measures, and post-swim support. Text of the briefing paper (in Italian) is attached, and a video of the brieing is available if need be.
Both entry into and exit from the water were unassisted as per IISA rules.
The swimmer had a smooth recovery on site, and no medical support was needed at any time.
Various videoclips were shot at each turn around both buoys and can be made available if relevant
