I think that was the hardest thing I have ever done. I just completed an 'adventure race' in a team of 2 with my team mate Malachy who is a regular triathlete whose ambition is to run an Ironman race.
We started at Gassan Golf course in Lamphun : run 380 m to bikes across a cute old narrow gauge railway bridge biked for 1 km did a 200 m swim rode our bikes for 12.5 km mostly on road did a 12.4 km 'adventure' run, we ran down to the water fall in Khun Tan national park and then up to Payap University guest house and then back down again. Mostly on forest trails. A lot of steep uphill. 12.2 km biking about half of it down hill, mostly off road. 1 km kayak course had a 2km bike ride on road to the finish line We finished in 3 hours 35 minutes. We came in 19th out of a field of 43. :-)
I plan to visit Angkhor Wat in Cambodia for the first time at the end of this year and take part in a 10 km mini marathon running around the temple area. I think that will be a great way to see Angkhor Wat for the first time. I reckon running around 10 km and running it as fast as I can is about the furthest I want to run.
I have set up a really great home gym for myself. This Concept2 rowing machine is one of the last of a few pieces of really nice pieces of equipment I have got hold of at fairly reasonable prices.
A rowing machine workout apparently is a great way to quickly hit several of your metabolic pathways and is a particularly beneficial because you are using so much of your body.
This was a 500 m sprint. I managed a time of 1 minute 29.5 secs which is really excellent considering I just took delivery of the machine today. My technique could certainly be improved but I my time is near to what I think is the world record of 1:18!!
