Seemingly most logical advice I've received thus far: If you can make the run your strongest leg of the event, you'll be better off. The most successful endurance triathletes come from a marathon base (Capitol City 2003). Why? Because mentally it is important to look forward to the run after completing the first two legs of the event.
Almost every other Ironman I've talked with agree that your strength and attitude about the run is a big factor in determining whether or not you'll finish the race. (I will.)
As a result, I'm in training for the Seattle Half Marathon (T-day weekend). Other "tools" of the trade:
Basic Requirements to Having a Good Ironman - Preparation, Patience, Optimism
36 Week Ironman Training Program
The average hours per week devoted to training for the World Championship generally fall between 18 and 22. (For comparison, I spend approx 10/wk now.)
Average training distances for the three events:
Miles per week swimming: 7 (11.3 km)
Miles per week biking: 232 (373.3 km)
Miles per week running: 48 (77.2 km)
Glad you're living vicariously?
Next installment: review of off-season strategy, hopes & fears, e.g. OMG I can't even sit at my DESK for 7 hours, HOW am I going to sit on a bike for that long?
45 wks & counting...
