A six hour is similar to the 24 except that usually they use a smaller race course...

your pre-ride will determine how long each of your lap will take...

since its a shorter race transitions should be quicker, ie be ready for when your partner comes in.

as for eating, its really more like snacking lots - eat what makes the tummy happy, my recommendation is NO FRUIT! but thats just my own opinion.

6 hours are fun, they tend to be more relaxed.

i did my first solo at an 8 hour. our transition area was through a barn, it was pretty fun.

ride safe
