I don't enjoy watching those shows, although my riding partner really enjoys them. I was given a sour taste when I watched something similiar last year or so. A husband and wife were losing weight, they had a trainer to help them with everything. They "completed a marathon". He swam 500 yards I think, with the floaty board as he got tired, the wife biked 12 miles flat and the trainer completed the 3 mile run. THEY were credited for completing a "marathon" and they were telling everyone they just completed a marathon. NOT in my book...last time i watched one of those "reality" shows. Yes, wife and hubby lost weight which was great, and they completed some goals, but it wasn't reality...ok, its just mho..
