Question about 20 week marathon training program

Greetings--I just purchased 20 week Marathon Training Plan and am excited about starting. I noticed that the duration of  endurance run workouts  never exceed 1:30.  I am aiming for a 3:45 marathon. So no longer duration runs in the weeks leading up to my race(20-21 miles) ?? I am assuming that strength/endurance/efficiency developed during the 20 weeks will be enough to carry me through that distance.

Also, I plan to do most of my training on trails because I find it more enjoyable, but my marathon is on the road. Do you think I should do any workouts on the pavement?

Any input would be appreciated.

Thanks Eric, I will incorporate those into my workouts.

Yes, you should be doing some road work as too much trails will not allow you to get the recovery needed.  So keep the easy days/recovery days on road and some of the faster runs on roads sporadically to train for leg speed.  Again, doing too much trails will slow you down.

To follow up on this, I'm using the 20 week program to train for a trail marathon, I've been strictly running trails during my workouts.  Should I be throwing in some pavement work?  I pretty much was working under the philosophy "train as close to the conditions you will be running in as possible".

Hi Barb - Since your race is on road, I would do the majority of your longer runs on road to simulate road/race conditions.  For peak performance, you want to be as specific as possible. I understand the trail enjoyment, but trails will not foster speed like the road.  So maybe alternate weekly so you can get this leg speed/turnover on the road.

My mistake, looking closer at the program I see there are longer 20 mile runs later in the plan. Would still appreciate input on trail vs. pavement running.
