I've done the challenge walk twice (2004 and 2005). To me, the biggest challenge was raising the minimum 1500 entry fee! I managed both times and it was a wonderful experience.

They provide you with a training program and you have the option to meet up with others who are training in your area. I did most of my training on my own but towards the end met up with a wonderful team captain who became my walking buddy and has since become a great friend.

The first year, I trained exactly as per the program. Every day, logged tons of miles. The weekend before the walk, I logged an 18 mile day. On the weekend of the walk, it was hard, but not impossible and as one of the very few people who didn't get blisters - I think the training paid off.

The second year, I didn't train nearly as hard. I think my longest training walk was 12 miles. Funny enough - it wasn't any harder than the previous year!

Blisters and dehydration were the biggest issues - they took most people out. Good running shoes in a half size bigger than you normally wear, some moleskin, and water bottles on a fanny pack are the tools you need.

Many people without MS couldn't finish it. I was so proud that I did the whole thing and I was really proud to wear that red shirt on the final day at the conclusion (only people with MS got red shirts). Goofy me, I'm getting all choked up about it right now!

I would encourage anyone to try it - it's not about how far you walk - as long as you start. You certainly won't regret the experience!
