10K-run training

I am training with my friends for a 10 km run. How much time to run 10 km? Hmmm, the 2002 world record is around 30 minutes. That is, around 3 mins / km (or 5 min / mile). My speed is around 5.4 mins / km (or 9 min / mile), running on track. I hope to improve my speed to 4.8 mins / km (or 8 min / mile) within 1 year.

Yesterday was my first time to run uphill. That was TOUGH! I became very tired when going uphill. I even have headaches after I ran to the top... Not enough oxygen for my brain :P Definitely need more traning!
