At 32 you are likely to be at the younger end but suggest you use the "ask the editor" and Olly will give you the age range of those that have booked so far (although its early and maybe a lot still to book).
I did this trip a couple of years ago and their was 18 (thats low for this hol I believe) of us with ages ranging from 27 to 77.
Different ages do mix well on these holidays from what I've experienced so if the chance of been the youngest is not a major issue dont miss out on what is a fantastic trip.
