3 days is just right then.   You guys will have a blast.  If you have any other questions on it fire away.  Lots of guys on here have ridden it multiple times.

We do not want a 500 k day - at least not for me on those trails anyway: Cochrane etc. - sure, but not on the RAP. I am thinking 200 to 250 miles a day is a decent day for us - if we make good time and have great conditions, we can take some other loops or ride around our night destination and extend if we wish,  but also leaves us a reasonable day should we meet some crap along the way - want a longer lunch- take some photos etc.:   We're looking to have a good fun ride father and son - not looking to break any mileage records.   This will be my son's first "trip" experience. I want him to have fun    

Depending on the weather and temp and also location of the trip, we typically do 350-500kms a day. I believe that trip averaged around  300-350kms/day.

What is a normal day’s mileage for you guys?  I’d say 3 days is about right for most groups.  Have done it in 2 which was too much.  3 days allowed us to do an extended loop starting well south of the park near Cloyne.  That was a reasonable trip.  

2 of us did a modified RAP last year. Parry Sound to Barry's Bay day 1. Then Barry's Bay to Rolphton across into QC the up the 43 to Temiscaming QC day 2. Then Tem across to North Bay and down to Port Loring and home day 3. Day 2 and 3 were -35C in the morning but made good time riding at a steady pace. left Tem at 9:30am on the last day and were home in Parry Sound at 2pm.
