Jon has competed in triathlon to a high standard for many years and is our resident Ironman. For those who do not know, the 'long course' triathlon distance comprises a 2.4 mile swim followed by a body-breaking 112 mile bike leg - and then concludes with the small matter of a full marathon distance run of 26.2 miles.
These events are truly tough and require incredible physical and mental endurance.
Jon has entered two half distance and one full distance event in 2015, and in doing so makes the truly tough almost incredible. Why incredible?... well; Jon has had a few health issues this past couple of years and in the summer of 2014 had to have major heart surgery.
The two half-ironman distance races scheduled are for next May (Belvoir Castle and the Outlaw Half), and the full distance event is the prestigious Challenge Weymouth - due to be run in September.
If he can complete the full distance Challenge Weymouth event, Jon could make medical history by becoming the first person with a pacemaker and artificial heart valve ever to do so.
