Struggling with Cycling
So I am training for my triathlon in May, which I know isn't that far away but am really struggling with the bike training. I am a complete newbie to biking as have always been a runner. My bike seems to be fine and is on the smaller cog when i change gears ( hope this makes sense) and I am struggling to do six/seven miles which, reading these comments and threads is no way near what i need to be doing! Where I live is exteremly hilly but, even so i dont think i should be struggling this much! (I can run about 5 miles with ease, and swim quite well). Any ideas would really be helpful!
