I just finished the C25K and am pumped about continuing this new hobby.  I need a watch to log times and to guide me through intervals.  I have been looking at the Timex Ironman watches but can not tell if you can set different interval times (like 3 minutes then 5 minutes) or does it just keep repeating a single segment.  Anybody have suggestions for an affordable sports watch?  I'm trying to keep the price under $60.
