First of all im new to the forum so hello everyone.
On friday I just finished my 1st half marathon in Tel-aviv marathon.
It was a great event! I trained for the past two monthes using cool-running's free begginer training plan from here:
http://www.coolrunning.com/engine/2/2_4/134.shtml
The race was very hard for me due to a back pain that started 10 minutes(!) before the race 
I managed to finish the race in 2:7:24, with a tremendous effort and pain.
I'll take care of my back and recover but now I really want to try train for another half and finish below 2hrs.
so what do i do now?
start the beginner plan all over again?
start the intermidiate?
when can I run my next rece?
Thnks!
