if you want to train, it's pointless doing it on London roads: too much traffic/red lights to get any sort of interval training going. find a circuit with no traffic (richmond park, regent's park, finsbury park etc) and train around it.
intervals are your friend. vary the time and intensity. you should train properly at least 3 times a week if you really want to improve.
i personally reckon if you can do it for a minute, it's not a sprint. but that might be my track runner prejudices, and bike training may be different. but i reckon a real sprint is less than 30 seconds. multiple reps of around a minute is a lactic session.
