I have done well on the plan - have done it religiously, never not completed what Laura has asked and always felt that is was achievable, albeit hard. Today was different - I really struggled (it was run three of week 7 so surely I should be used to these 25 minute runs by now?) What's worse is I have mapped my run and found that in 25 minutes running I am only covering 2.2 miles (about 3.5km), so clearly I'm running very slowly. My route is flattish. Only 2 weeks now from the end and 5k seems very unachievable. what sort of change can I expect in the last two weeks? By the way, I am only 5 foot 1 so does height affect the length of stride and therefore your pace?? Or am I just looking for an excuse?
