Time is Money

Price of my time per minute: £0.15

Reward for filling out Cambridge Cycle Challenge survey: Entry in drawing for £40 gift card to Marks & Spencer[1]

Time to fill out survey: 4 minutes

Number of challenge participants: 2422

Maximum number of survey respondents to make it not a waste of time: 67 (2.8%)


  1. Due to the amount of shopping we do at Marks & Spencer, this is functionally equivalent to £40 cash.
