It cannot be stressed enough that race nutrition is critical to a personal best performance for the longer races, ½ ironman and beyond. You have got to know what your needs are prior to race day. Rehearse your hydration, feeding, and salt strategy during your training sessions. There are so many variations between individuals that there is no single right answer.
To help you determine your nutrition needs, Ayesha and I are running a nutrition seminar this Thursday Aug 8th, 7:00-8:00 PM at the Trek Store on Yonge. The talk will cover how to calculate your sodium needs and why you need to take it as well as carbohydrate and protein requirements pre, during and post race. There will also be a section on nutrition specific to marathon running from Michelle Clark who is the local Clif Bar rep (and a sub 3:00 hour marathoner). She will be giving away Clif product. If you would like to attend, please send me an RSVP at email@example.com
As a side, last weekend I did the Kempenfest 2k swim in Barrie, some pics are below. It was a fun chilly swim, swimming with Ayesha (7 months pregnant) and a bunch of swim camp kids (12 year old girls can be aggressive). For the record Ayesha still kicked my butt.
