I have my first marathon coming up in 3 weeks and I am still unsure how to go about pacing on race day. Any advice from marathon runners would be much appreciated.
Here is the low down:
I have done quite a few half marathons now and decided to step it up this year to marathon distance. I ran the Bath half about a month ago in 1:21 and have a target time of 3:05 for the marathon. My pacing for the half was horrific passing through 5km in 17:40, need I say no more. Many have told me that I should try to even split the whole race, but I feel I will not be able to hang in over the last 10km.
The pacing plan: 0-10km pace 4min / km, 10-20km 4:10 / km, 20-30km 4:20 / km and 30-end 4:30 /km. This would give an overall time of just under 3 hours.
Is this a good idea?
