Snowtulip,
Just get on a team that has a good attitude, and go for it. The attitude is really the whole battle. Now don't get me wrong, I am very competitive, BUT, for this race, I had a different mindset, and I really just wanted my team to finish the 12 hours and do our best. Which we did. So getting on a team that is going to be supportive of your performance...that is the key to a good day.

Now as far as training. I just did an adventure race last month, so I just kept on training. Running, biking, lifting. I tried to do some rides at race pace, as hard as I could go for X amount of time, usually 1-2 hours. Other days I tried to ride a little slower and go longer.

Depending on the size of your team, muscle endurance is KEY. So you need to have a strong base.

Does that help????
