NI Newbie - Should I start running now?
I've signed up to do a try-a-tri in June, consisting of - 250m open water swim, 20km bike, and 3km run.
Am already a fairly consistent swimmer - doing 30x lengths (750m, mixed strokes) in local pool 3-4 times a week. I can ride a bike, but have never done so competitively, and am pretty clueless about gears, style, technique etc. Running-wise, I did a couch to 5k a couple of years ago, but had to jack in running due to knee and achilles problem.
On that last point, I should add that I'm a very big guy - 21.5 stone/6ft 3ins tall - and am using this triathlon as a motivator to lose weight. My physio told me that I shouldn't be running at the weight I'm at, as it is having a bad impact on my joints - rather, I should lose more weight BEFORE I start running.
The problem is, all the training plans I've seen insist you do all three disciplines from the off. But am I better just training in swimming and bike for a couple of months and then starting running once I have a bit more weight off/am a bit fitter? Or MUST I train in all three from the very beginning?
Would appreciate any thoughts on this - it's been a real goal of mine to do a triathlon, so I am feeling very motivated.
