While us worker bees can get in 30K/week w/intervals for a 5K of comparable quality to 60K/week w/tempo for a Half, running 110K per week including quality speedwork for a Marathon would get most of us fired and/or injured;<br /><br />2) For you - perhaps some yet unrealized capacity for a great result. it is hard to train and finish the Marathon 0:15/K off Half Pace as McMillan would assign. But 0:25/K off Half Pace for a Marathon is very attainable for a recreational Marathoner...especially on a favourable course like Toronto.<br /><br />I took a look myself, based on my 5K or Half times, McMillan sez:<br /><br />5K - 4:16/K (PB is 4:16/K)<br />10K - 4:26/K (PB i 4:22/K downhill)<br />Half - 4:42/K (PB is 4:42/K)<br />30K - 4:49/K (PB is 4:54/K)<br />Mar - 4:56/K (PB is 5:06/K)<br /><br />Mind you these times can be a self-fulfilling prophecy as I will use McMillan to help pace the early parts of races.<br /><br />I'm going to try to narrow the ga on the last two distances above to 4:50/K and 5:00/K this spring. The Toronto Marathon on a downhill course will help. We'll see how it goes.Double Bellybusternoreply@blogger.comtag:blogger.com,1999:blog-5603310121784038818.post-57869576117486212062013-03-04T09:43:45.196-05:002013-03-04T09:43:45.196-05:00No doubt the predictions are so general to the poi...No doubt the predictions are so general to the point of being useless, except perhaps to help you set a reasonable target. <br /><br />All these calculators say that extrapolating a 5k time to a marathon only "works" if you have built up the endurance through training.<br /><br />I can't share my results (with calculator and actual pbs) because I've never raced a 5k or 10k (except as a leg of a triathlon.)<br /><br />Based on yesterday's half marathon I can do a 3:12 full (agree), A 41M 10K(agree) and a 19:43 5K (seems too fast).John Chttps://www.blogger.com/profile/15348002052380879261noreply@blogger.com
