To help you prepare for the club marathon on April 30, you might like to follow this guide.
This is an “intermediate” one. It should be fine for all regular runners (not beginners) so will be okay for club members. The better runners might like to do a more advanced schedule.
This schedule has the long run on Sundays, so if you are doing the club races (and we hope that you are) you will need to do your long run on another day – Saturday perhaps..
