We did running last month. This month we thought we would try cycling. The final stage of the Tour de France is 80 miles or 128km. Last year this took place on the 28th July. So your challenge is can you cycle 80 miles (128km) before the 28th July? Of course, you may choose to cycle further, if you want a completely loopy challenge the furthest distance cycled on the Tour de France in one stage is 230km!!
