Double or quits?

Recently I came across an article by Duncan Larkin on the Running Times website questioning the benefits of double days and instead singing the praises of only running once a day – you can read it here. Now many runners, me included, believe that the best way to increase mileage – which results in weight loss, improved running efficiency, capilliary growth, increased cardio-vascular efficiency, etc – is to run twice-a-day as many days as possible. Indeed I know that before Ryan Hall met Matt Dixon he was sometimes running three times per day. One of the things that Matt suggested to Ryan is that he reduced the number of runs he was doing. OK so I know that is an extreme example, but the article by Larkin describes the incredible results of Yuki Kawauchi, who became the first Japanese runner to cross the finish line at the 2011 Tokyo Marathon in 2:08:37. Kawauchi works full time and can only manage 1 run per day.

Generally my weekly programme is;

Monday – one run
Tuesday – double day: easy run and then session
Wednesday – one longer run
Thursday – double day: easy run and then session
Friday – rest day
Saturday – double day
Sunday – long run

However Larkin’s article quotes Marathon Performance Training Group’s elite coach Brad Hudson, who says that the key is to run for more than 80 minutes, which triggers certain physiological changes that are ideal for endurance athletes and especially marathon runners.

So what to do? I love my long and mid-length runs and would happily drop a 30 minute recovery run in order to fit in at least one more run of over 80 minutes. But then that could easily be the route to injury if the increased mileage is not managed carefully. Actually I suspect that my coach will increase my mileage as we approach the Seville marathon in February and that will probably mean at least two 80+ minute runs per week, so I probably don’t need to worry. But for those of you considering double days but wondering how to fit them in, how about adding to one of your existing runs and making that a mid-length run. Who knows… maybe 2:08:37 could be on the cards!
