Interesting section between Edney Common and Ivy Barns... its COR in various grades. Hard pack & falling apart tarmac at the start, fast downhill on concrete slab sections (OK for 1.25inch tyres, not tried it on 25mm!) and then shingle at the bottom where the houses are on Ivy Barns.
On the way home probably quicker to head (downhill) in to Writtle and back out to Chelmsford, though you do have Ivy Barns Hurt Locker to contend with...
Slightly more pleasant approach adds a couple of km on. Home section is about the same distance but should be quicker

You could save a few km skipping Newney Green and coming up The Causeway thus:

New London Road is no right turn as it gets to Parkway, so you might have to be creative...
