Brain Teasers

1. Yesterday I went for a long bicycle ride around the local lakes. As the ride was quite long, I rode in various stages.
In the first stage I rode half of the overall distance.
Stage two saw half of the remaining distance plus 35 metres covered.
Stage three covered three-quarters of the remaining distance.
Stage four completed half of the remaining distance plus 75 metres.
Stage five completed the journey with a final burst of 150 metres.
How far did I cycle in total?

2. At the recent Sports Festival, the 100 metres heats were closely monitored.
Each contestant had to run in two races so that the average place could be determined.
Only one runner finished in the same place in both races.
Abhay was never last. Charlie always beat Darren. Bharati had at least one first place. Abhay finished third in at least one of the races. Both Dilkush and Charlie had a second place.
What were the results of the two races?
