Just can't get faster
So I was unfit before April, only doing rock climbing, no cardio so to speak. Since I signed up then for the London OD I have been really trying hard to get some level of base fitness. I couldn't swim or run and could bike (but hadn't in years and only did MTB before anyway). Now I can do the distances fine and to be honest I am really proud of myself. I know my times have dropped but am still feeling very demoralised about how slow I am. I guess I shouldn't get down b/c I have made dramatic improvements in a relatively short space of time, but I am a bit. I've been reporting to Coach Coney on my TTs of each discipline of late and they are just awful. I seem to have one speed no matter how fast or far I am attempting to go. My 10k is about 63 minutes now which is exactly double my 5k. Why is my 5k not faster even when I'm trying? I cannot push myself on the bike at all, I'm on a MTB with slicks which I was fine with at first but now I get on it with disgust of 'oh if I was on a road bike this would be faster', which to be honest is probably not even true! I trudge along getting bored but also not going any faster and it takes me like 1 hr 40ish minutes to do 40k which is so embarrassing it is difficult to admit. My swim is much the same, always around 35 give or take a few minutes either side. Sometimes I can crank it up if I get lumbered into the fast lane with good swimmers and am trying to keep up, but then often get so out of whack trying to keep up I don't count my lengths so who knows what my time is then. If it is just me swimming, I'm slow. I guess my question is how long does it take to build up a decent level of fitness where you can start really pushing yourself, and how do you do it! London is only a few weeks ago and I'm still scared I won't finish or something horrible so fathoming really pushing myself is quite difficult. I'm probably just being a wimp and staying in my comfort zone but dont' know how to get out of it. Help!!!
