I have been running for approx 12 mths and done 1 x 5k, couple of 10k's, 2 x 10mile, and 4 half marathons. My technique is to run all the way irrespecitve of how tired I feel, but some people walk and then pass me later, appearing to be quite refreshed. I fear that once I stop I will not get going again at any reasonable speed anyway. Any suggestions on which works, run all the way or run and walk?
After I have done what I feel is a fast run and put every ounce of effort into it with some speed training to try and improve my overall speed, within approx 30 mins I feel extremely sick. I do eat after my cool down / bath ie jacket potatoes with tuna. But it takes me a long time to recover and am not really feeling well enough to do much but sit down. Any suggestions.
