I first ran on the Londonderry rail trail back in the late 1980's when it was a rough dirt path and in places still had RR ties. I've been on all of the trail from Lawrence to Exit 5 in Londonderry in recent years but had yet to check out North of Exit 5. Yesterday I headed out on the newly paved section. It was in great shape and quite scenic. I parked near Poor Boy's and headed North on the trail. The paved section ends at the Middle School after 1.5 mostly shaded miles. From that point I crossed over route 128 and went up Mammoth road before getting back on the trail. It looks like this part has had some work done as the next 3/4 miles has the ties pulled up (and piled next to the trail). The final 1/2 mile is a bit rough with the ties still down but has had a lot of use so it is mostly easy to run. The trail ends just under 3 miles from the start at Harvey road at the Manchester airport.
For a little change I ran back on the gas line right-of-way which runs parallel to the RT from the airport to Mammoth road. It is also run-able but a bit grassy in spots. All in all this was a great place to run. Some day I'll have to take on the whole 20+ miles from Lawrence to MH or maybe bike the round trip?
