As a group of 54 - 72 year old walkers, we found this walk quite challenging in parts, there are a lot of hills!! The track can be fairly rough in parts so you need to watch your footing, our four days walking were broken into 14k, 21k, 35k(ridiculous) and 21k. I had envisioned coming back at sometime and mountain biking the trail...no way!! If you plan to ride, as previously mentioned, there are hills..big long hills which you may find walking is the only option, parts of the trail are very gnarly plus you have to contend with walkers on the sometimes narrow trail.This trail is for advanced riders only and MSAC have a duty of care to advise clients of this, on our last day walking, two people had taken falls off their bike due to inexperience.
