The fatigue has really set in after 60 Olympic-distance triathlons with no break.

Number 61 was a test of surviving the three or so hours of exertion, desperate for the time to pass so making as much effort as possible to go as fast as I can, while feeling extremely drained.

Thankfully the knees and calf muscles that have caused much concern over previous weeks give only occasional reminders of their weaknesses.

I completed today in pretty standard times (30 minutes for the 1,500m swim, 1 hour 10 minutes for 40km cycle and just under 49 minutes for the 10km run). However, the rest of the day was a wipeout. I was doing better when I had just four hours sleep over Christmas, or perhaps I am now paying for those days.

However, I am buoyed by the fact the number of triathlons left to do begins with a three for the first time, another ten and I will really feel like I am on the run in.

I am completing this massive challenge to raise money to build a fitting tribute to all police officers and staff who make the ultimate sacrifice on our behalf. If you have not yet supported me please donate whatever you can here.

Today I paid tribute to all who died in the line of duty on December 30. They are:
