Hello all,
I'm 14 and have been into serious cycling for about half a year.
I can maintain good pace on the flats (40-45 kph) for a decent time period, maybe a half hour before I start to hurt, and my acceleration up the hills is good (maintain 25-30kph up some seriously steep short, sharp ones around home), but have no real mountains close enough for me to train regularly, and so far as I can tell, going up the short hills only seems to build strength and bulk rather than endurance, so what can I do?
