I just wrote about my race plans for next year and didn’t have the Henley Swim inĀ (Sun 10th July 2016). My plans might change and, to be honest, I also forgot to add in the River Arun 3.8km swim.
Henley has various distances: 2.1k upstream and a 14k bridge to bridge (I’ll NOT be doing that!!) and the Henley Mile (that’s more like it).
River Arun (Sat 18th June 2016) benefits from being Ironman distance. Although with a good tidal flow and swimming downstream very many of you should be easily able to do it in under an hour.

My favourite kit and nutrition
- Injinji – Runners protect your toes. Avoid discomfort and minor injury. Run more. Run faster. I use them.
- Garmin 90-degree charging adapter ā The small adapter that keeps your charging cables tidy. Essential for race day. I use one.
- Garmin charging puck ā the fastest and most reliable way to top up your Garmin before a session. I use one.
- Ravemen FR300 ā Front light that mounts directly under your Garmin or Wahoo head unit. Keeps your bars clean and your beam pointed where it matters. I use one.
- Body Glide – The blue anti-chafe stick that all swimmers and many runners use. I use it.
- Maurten ā The race nutrition trusted by elite athletes. Gels and drink mixes engineered to be easy on the stomach. I use them.
- Garmin Varia RTL515 ā A radar rear light that alerts you to vehicles approaching from behind. Pairs with your Edge or Garmin watch. I use this model.
- Favero Assioma Pro RS2 ā The power-meter pedals most serious cyclists choose. Accurate, easy to move between bikes. I use this model.
- Garmin Forerunner 970 ā A serious choice for a pro-grade triathlon watch. I use this.

Is it just me or is nearly Ā£50 to swim a mile in the Thames taking advantage somewhat?
well. put like that. YES !! š Tho ask that bloke the other year from NZ who swam around the boats in Hammersmith…he got deported. Ā£50 would be a small price to stay in the country for him. (re: boat race)
