St Albans is an unusually good place to run for a town this size. Roman parkland with
a lake in the middle of it at Verulamium Park, a chalk river running north out of the valley, a former
railway line you can follow out of town without crossing a road, and at Heartwood Forest the largest
new native forest in England four and a half kilometres from the Abbey.
And it is gentler ground than the Chiltern edge above it suggests. Measured
against terrain data across the nine routes below, the flattest carries 4.4 metres of
climb per kilometre and the steepest 11 — rolling rather than hilly, with nothing
that counts as a climb. What St Albans gives you is variety inside a six kilometre
radius, not difficulty.

Asked for“an easy 5K by the water”
Verulamium Park and the River Ver
Verulamium Park and the River Ver is a 5.3 km loop in St Albans, and the only one of the nine that stays beside water the whole way. Past the lake and the Roman wall, with two crossings of the Ver.
Distance5.3 km
Ascent50 m
Steepest5.7%
On path34%
River VerVerulamium ParkRoman Wall
Why this one
64% of the climbing sits in the middle third — you start flat and you finish flat. 8% of it doubles back on ground already covered, and it stays within 1.0 km of the start.
The Alban Way and back through Fleetville is a 9.6 km loop out of St Albans along a disused railway, sealed and traffic-free. The Alban Way itself carries no road crossings at all; the return leg through Fleetville does.
Distance9.6 km
Ascent61 m
Steepest2.1%
On path30%
Traffic-freeAlban Way
Why this one
The climbing is spread evenly — no third of the route carries more than 35% of it. 5% of it doubles back on ground already covered, and it stays within 1.6 km of the start.
The Heartwood Forest loop is an 8.4 km run four and a half kilometres north of St Albans, and the most off-road of the nine at 89% off tarmac. Bridleway and woodland track through the largest new native forest in England. Unlit, so daylight only.
Distance8.4 km

Why this one
50% of the climbing sits in the middle third — you start flat and you finish flat. 89% of it is off tarmac, more than any of the other eight.
Asked for“something short, right through the middle of town”
Cathedral and the city centre
Cathedral and the city centre is a 6.5 km loop through the middle of St Albans, the most built-up of the nine. Abbey precinct, the market square, Holywell Hill and back along Verulam Road.
Distance6.5 km
Ascent70 m
Steepest5.1%

St Albans CathedralCity centre
Why this one
51% of the climbing is in the last third. It finishes uphill, which is worth knowing before you set off. Only 15% of it leaves tarmac, less than any of the other eight — it is the one to run when you do not want to pick your feet up.
Clarence Park and Bernards Heath is a 10.4 km loop out of St Albans City Station, and the one of the nine answered by what the route passes rather than where it runs. Loops were drawn on several bearings and this is the one that goes within 10 m of a public toilet, measured off the line rather than assumed from the postcode. 86 m of climb, and 16% of it off tarmac.

Ascent86 m

Clarence ParkBernards HeathFleetville Park
Why this one
65% of the climbing sits in the middle third — you start flat and you finish flat. It doubles back on itself more than the others do, though that is still only 15% of its length.
Ver Valley Walk to Redbournbury Mill is a 12.2 km run out of St Albans that follows the chalk stream and never leaves it. Watercress beds, and the working mill at the far end.
Distance12.2 km
Ascent128 m
Steepest5.4%

River VerTrailVer Valley Walk
Why this one
The climbing is front-loaded: 45% of it inside the first third, so the run flattens out as it goes. 6% of it doubles back on ground already covered, and it stays within 1.9 km of the start.
Highfield Park and Jersey Farm is a 7.3 km loop in St Albans and the flattest of the nine by some way: 32 m of climb, never steeper than 1.7%. Two parks joined by quiet residential streets.

Why this one
There is barely any climb to place: 32 m across 7.3 km, and never steeper than 1.7%. 4% of it doubles back on ground already covered, and it stays within 1.1 km of the start.
Nomansland Common is an 11.1 km loop north-east of St Albans, two thirds of it off tarmac and the most open of the nine. Heathland, grass and gravel, with the long drag up from Sandridge doing most of the climbing in the first third.
Distance11.1 km
Ascent103 m
Steepest5.2%

HeathlandHillyDaylight only
Why this one
The climbing is spread evenly — no third of the route carries more than 43% of it. No part of it is run twice — the loop never comes back on itself.
Asked for“half marathon without repeating a kilometre”
Ver valley half marathon
The Ver valley half marathon is a 22.0 km loop from St Albans with no kilometre repeated. Out along the river to Redbourn, across the fields to the Nickey Line, and back down into town. It is the only one of the nine that gets you race distance on a loop.
Distance22.0 km
Ascent196 m
Steepest5.3%
On path25%
River VerTrailHalf marathonLoop
Why this one
The climbing is front-loaded: 47% of it inside the first third, so the run flattens out as it goes. It goes further out than any of the others, 3.1 km from the start at the far point.
Each of those nine started as one sentence. Tell RunFlex the distance, the surface and when you need to be back, and it draws one from your front door — not from the middle of St Albans, and not from a list of runs other people have already done. If it isn’t right, say what is wrong and it draws another.

Daylight in St Albans, month by month
Sunrise to sunset
The other thing that shapes a run here is how much light there is. The sun sets at
15:51 in mid-December and 21:21 in
mid-June, so the same after-work hour is a summer evening or a
night run depending on the month.
Computed for St Albans at 51.7520°N 0.3360°W, on the 15th of each month in 2026.

Try it on your own run. Say the distance and the surface, and RunFlex drafts it from your front door — not from the town centre, and not from a list.
Verulamium Park is the obvious start: flat, paved, beside the lake and the River Ver. For distance without road crossings, the Alban Way runs east from the centre on a disused railway line. For trail, Heartwood Forest is four and a half kilometres north of St Albans. All nine routes above start from the centre, and RunFlex will redraw any of them from your own front door.
Where can I run 5K in St Albans?
Verulamium Park is the obvious 5K in St Albans: flat, traffic-free, past the lake and the Roman wall, with the River Ver alongside for most of it. St Albans parkrun uses the same park at 9am on Saturday — three anticlockwise laps, predominantly grass, after an uphill start.
Is there a traffic-free running route in St Albans?
The Alban Way. It runs 10 km from St Albans to Hatfield on a sealed surface with no road crossings, so it works as an out-and-back at any distance you choose.
Where can I run in St Albans without a car?
Every route on this page starts inside St Albans, so none of them needs a car. St Albans Abbey station sits at the western trailhead of the Alban Way, which runs to Hatfield without a road crossing, and St Albans City station is about a kilometre from Verulamium Park.
Where is St Albans parkrun, and what should I run the rest of the week?
St Albans parkrun is in Verulamium Park at 9am on Saturday, starting on the grass near the basketball court — three anticlockwise laps after an uphill start, predominantly grass. Heartwood Forest parkrun near Sandridge is the trail alternative. Midweek, St Albans Striders run from Abbey View Track on Tuesdays and Thursdays, and Athena is a women’s club in the city.
What is the flattest run in St Albans?
The flattest run in St Albans of the nine on this page is Highfield Park and Jersey Farm, at 32 m of climb over 7.3 km and never steeper than 1.7%. The Alban Way and back through Fleetville is next, at 61 m over 9.6 km. Both figures are measured off the drawn line rather than estimated from the map.
How hilly is St Albans?
St Albans is rolling rather than hilly. Measured across the nine routes on this page, the flattest carries 4.4 metres of climb per kilometre and the hilliest 10.8, and the steepest single pitch on any of them is 6.3%. The climbing sits in the valley sides rather than in any one hill.
When does it get dark in St Albans?
In St Albans the sun sets at 15:51 in mid-December and 21:21 in mid-June. The clocks go back on 25 October 2026, and sunset on the Monday after is 16:45, so from late October most weekday running here happens after dark. The month-by-month figures are in the table above.
Where can I run after dark in St Albans?
In the centre of St Albans and out along the western Alban Way the streets are recorded as lit. North of Sandridge none of them are: every way up there that carries a lighting record at all is recorded as unlit. Heartwood Forest and the upper Ver valley have no lighting, so treat those as daylight runs whatever the hour.
How many running routes are there in St Albans?
There is no fixed number. The nine above are examples, each one drawn in answer to a different request. RunFlex builds routes from the St Albans street and path network rather than serving them from a library, so the number available is as large as the number of things you might ask for, and it starts from wherever you are rather than from the town centre.
Nine of an unlimited number. Yours is not drawn yet.
Say the distance and the surface. RunFlex drafts it from your door and sends the one you pick to your watch. Ask again tomorrow and you get a different one. Free early access while it is being built — no card, and no price to pay yet.
RunFlex is built by Rob Gotlieb, who runs. The nine routes above were
drafted by RunFlex from the St Albans street and path network, measured by the same
services the app uses, and read by a person before this page went up. Nobody has run
them end to end — that is the trade in the table above.
If something here is wrong, and on a page of nine drafted routes something
eventually will be, tell us and it is fixed on the next build rather than sitting in a
comment thread.
