Hi Seb, and welcome
Check some of the threads in the Training sub-Forum, such as "Increase speed".
Once you read through those threads (not all are useful to your situation but some are), you'll have a better idea of what to do.
There is a lot of information there.
Any doubts, just get back here and for sure you'll find help.
The site
www.pponline.co.uk has a lot of good articles as well.
It may help us to know:
Your height/weight.
How much time you can dedicate to training.
Two months is not a long time... but it may be enough for all you want to achieve.
