clutch strange for a mile or so

Took the car out today in the continuing sunshine we have at the moment , and for the first mile or so the clutch felt strange. It felt like the first few inches of depression of the peddle was only spring, then it felt normal the rest of the way in. The clutch appeared to operate normally, just felt like strange. It returned to normal after a short period of gear changes. are their any lubrication points on the clutch assy i could do. Thanks
