Rowing is such a great hobby because it such a great cardio workout.  How did you get involved?
Initially I rowed at my local club however I have done the majority of my rowing at school. This allowed me to participate in events such as the National Schools Regatta which is held at Eton Dorney Lake.
That is cool!  It seems like it can be very relaxing and peaceful, at least when you're not in competition.
That's why I like it so much. In summer I can relax on the water with my friends, but I can also compete to a high level. I prefer regattas over head races as they're much shorter and provide a greater adrenaline rush. 
The adrenaline rush is what makes competition fun.  There are also great social aspects of competition, do you find you meet interesting people when rowing?
Aside from my peers and coaches who I have built very strong relationships with I have also had the opportunity to meet many professional athletes including Olympic Gold Medal winner Zac Purchase who went to our school and I have been coached by Eric Murray, another Olympic Gold Medallist. Outside of rowing I have also spent an evening with Sir Steve Redgrave who is arguably one of the most successful sports persons ever (and is also a rower!). 
Wow, you have met some incredible people!  Didn't Sir Redgrave win gold medals in five straight Olympics?
