Hi there.
I have found this particular thread rather interesting. As a newcomer to the forum i have been quite suprised by the amount of miles some are running per week in their training. I have personally never tried the method of increased mileage, however i can defintley see how it could lead to improvement.
Around 2-3 years ago, i was running quite competitively for my school and local club at the age of 15. My training mainly consisted of a few casual steady runs, intervals and hill reps with a main focus towards cross country racing. Just after the cross country season finished, i began to go down to the track and start training for summer athletics. After a couple of weeks training down at the track, i found that i needed a bit of a change and so entered for a local 5k with no real specific training. I was majorly suprised when i came through the finish in 17:36.
Of course, different training methods suit different people. But i thought it would just be interesting to share my rather unconventional training methods with you!
Well done on your recent progress anyway! It sounds like your defintley on target for some seriously quick times!
