| For those unfamiliar with the sport of rogaining, it is a gruelling physical endurance event. |
| But in a strange way, it added a level of realism that we wouldn't have got, gruelling though it was. |
| Sprinkled with gruelling technical climbs, crazy downhill flings, and easy-rolling side hills, this trail is excellent for all levels of riders. |
| The gruelling climb will see the participants scale heights of 4000m in very difficult conditions. |
| The scenery was breathtaking and it was a very enjoyable walk if a little gruelling at times. |
| And Grant credits a gruelling pre-season training schedule with giving him the leg-up he needed to prove a point. |
