Running Times in and around Greenwich

South Dock

28th December 2013 (updated January 2015)

I really enjoy going along to British Military Fitness Running Club on Wednesday evenings on Blackheath. I find that running with a group pushes you to run much harder than you would ever try when running alone. Every week is different but they often include some timed circuits. I keep forgetting my times but have now decided to jot them down here for reference.

If anyone is thinking of trying these routes, to set your own target, my fastest flattish half marathon time is 1 hour 46 minutes and I am noticeably slow on short sprints. Every time we do a new circuit I’ll try to add them and maybe add little maps if I can. I’ll also add details of any long runs in the Rotherhithe – Greenwich areas.

Greenwich Park Outer Circuit.

This is when the park is closed and you need to run the roads by the shortest possible way. Maze Hill is a long and gentle hill and Crooms Hill is short and steep. You can go either way.

My fastest time 18 minutes 20 seconds (some BMF runners can do this in about 14 minutes!) 131200

Greenwich Park Inner Circuit

Apparently this is 2.2 miles. When I lived next to the park it always seemed to take 16 minutes but hopefully it would be a bit faster now?

Maze Hill – Westcombe Park Road – Vanbrugh Fields – Highmore Road

A little all road circuit for sprinting

3 minutes 131200

Gloucester Circus

Good for pairing up, one person runs while the other waits.

50 seconds per lap is about my fastest but 1 minute per lap over four alternate laps is just achievable 131200

Thames Circuit through Greenwich Foot Tunnel and over Tower Bridge about 11 miles

This is my normal long slow run. I start at South Dock but it makes no difference. The run can be increased by adding bridges with London Bridge being a half marathon. A word of warning – although it is lovely running at high water there can be bridge lifts to mess up your timing. Deptford Creek, Limehouse Basin and Tower Bridge can all open up but are less likely at low water. The locks at South Dock and St Katherines don’t normally hold things up as you can run over the closed lock gate (on the assumption they can never open them both!). Other things to mess up your run are unthinking property owners who leave rights of way locked with padlocks and Tower Hamlet Council who for some reason insist on locking a Memorial Park (even on Christmas Day!) forcing you up onto a horrible main road. Also beware on Tower Bridge as the tourists often step backwards to get a scene in their camera causing a major trip hazard.

This is a great circuit to do with less able runners as a river bus connects everywhere so people can decide to go half way if they like.

This is generally treated as a long slow run.

1 hour 50 minutes 131200

1 hour 53 minutes 131225

About 2 hours 140201 – This time we ran clockwise and it provides much better views with a great vista of Tower Bridge and Canary Wharf when heading east. Sadly we ran in the evening and the path is virtually closed off by all the flat owners on the north bank who put up gates all over the place. Such a shame that the Thames Path hasn’t right of way.

1 hour 37 minutes 6.9 mph 11.17 M (that’s a record for me) 140625

2 hours 8 minutes 140810 (wow that was slow) 5.3 mph 11.25 M

1 hour 41 minutes 42 seconds (that’s better) 6.6 mph 11.15 M 140825

1 hour 54 minutes 04 seconds 6.1 mph 11.64 M 150101

2 hour 03 minutes 6 seconds 6.3 mph 12.90 M 150110 (over London Bridge)

Our neighbour has done this route in 1 hour 18 minutes but he is entering the Mount Blanc Marathon. Has anyone done the loop faster?

Putney Bridge to South Dock

This is a 12.42 mile run along the river, except by Battersea Power Station where you are diverted inland. Clearly marked but it get crowded along the stretch from Westminster Bridge to Butler Wharf and you need to run quite slowly to avoid the tourists. We did it as a long slow run. Sadly there are no hills!

2 hours 1 minute. Average speed 6.2 mph. 140119

Greenwich Park 10K – including triple climbs up One Tree Hill

This was a wicked route devised by BMF as a Sunday morning race. The route was complex, I got slightly lost right at the end, but it was a good and hilly run so it was excellent training with maybe 150 -200 m of ascent. The fastest in was 40 minutes and 9 seconds. My time was 49 minutes and 8 seconds.

South Dock to Greenwich Park with one full lap

I hour 10 minutes 18 seconds 6.3 mph 7.44 M 15011

Preparing Sumara – Stripping the Mast

26th December 2013 South Dock Rotherhithe

Sumara’s mast is now 23 years old and the varnish has never been stripped off. Despite a trip to the Caribbean and various trips to colder places the varnish actually looks pretty good. However each year there are two or three blisters which need repairing. When I prepare the blisters for primer coats it is obvious that the bond between the thick varnish and the timber is giving way. It would be possible to slide a scraper blade under the varnish and lift a much bigger area. Although I could leave major work on the mast for a few more years it seemed wise to tackle this job while the boat is next to home in South Dock before leaving on the Russian Expedition. There is very little evidence of water penetration so the timber all looks clear of staining. The mast is made from Douglas Fir as a hollow box glued with resorcinol resin and solid by way of the spreaders and winches.

I decided to take off only the necessary fittings but to leave the track and fittings around the spreaders in place. Using an AEG heat gun with two speeds and six heat settings I softened the varnish and lifted it off with an 30 mm wide Hamilton scraper – slightly blunted to avoid scratching. The thick varnish lifted off easily in sheets. I then scrape over the area again without heat using the brilliant Bahco Ergo Scrapers. It was interesting that the newly applied varnish (in the repaired blisters) was really hard to get off because it had better grip on the timber and less thickness.

For the most part the stripping was pretty trouble free but some areas lifted patches of the grain. This was hard to prevent even by scraping gently across the grain but it is limited to a couple of areas about three inches long. I’ll need to see what it looks like once the mast is sanded but I suspect it won’t be worth trying to fill or scarph in a grafting piece. It is possible that the grain lifted due to the timber being very slightly damp. All the more reason to get the old varnish off. I didn’t quite finish all the scraping on Boxing Day due to it getting dark but the process would be complete after eight hours work (the mast is 36 ft long).

That said, I think I need to spend another two full days to remove the fiddly bits and to sand the mast prior to varnishing. I am debating the idea of giving it a coat of preservative first. It will eventually be varnished with Epifanes Gloss Varnish.

I have invested in the Festool Linear sander which I hope will make the sanding process very fast (I need to sand between each coat of varnish too so that is nine x 36 foot!). I have to make up a profiled block for the linear machine which only sands with a back and forwards motion. The profile will match the curved corners of the mast perfectly. I hope to be able to sand the mast in two hours using this and other machines.

I’ll post some photos later and update as I go.

Russian charts at the CA

A Typical Section of “Canal”

6th December 2013

During our Russian Meeting No 1 at Kentish Town Graham kindly suggested that he may be able to arrange a viewing of the Cruising Associations collection of Russian Charts. On Friday evening Grit and I arrived at the CA to take up the offer.
Graham and Fay had found the folio of charts, maps and “atlases” which were stored in the loft and had arranged them in organised piles on a large table in the Committee Room. We had the luxury of a whole evening to study them.
The charts are of significance because they belonged to the first pioneer yachts to make the journey. Some charts were marked with Wallace Clark who was the father of Miles Clark who sailed White Goose through the whole canal system sadly dying before finally completing the journey. The book “Sailing Around Russia” was completed by Wallace Clark.

We had a variety of aeronautical charts, maps, navigational charts from British Admiralty and Russian Sources plus three “Atlases”. These Atlases were books of charts plus side elevations and diagrams and photos of bridges. These books were fascinating and contained everything needed to navigate the “canal”. I suppose naïvely I rather had the impression that the journey would be a matter of entering and leaving a canal into a big open lake and then entering the next canal. It is apparent from the charts and atlases that it is all a bit more complicated. The canal joins into small areas of open water and buoyed channels and even when you exit into a massive lake there are large shallow areas and areas ridden with weed and rocky outcrops. That said, certainly from these 40 year old charts, there are plenty of navigational markers to help us on our way.

Looking at used charts has the benefit of being able to take heed of various notes written on the charts. Even knowing which town is which is tricky without a copy of the Russian alphabet to hand. Markings pointing to reporting Radio Stations reinforce the need to have Russian speakers on board.

Grit and I have taken extensive notes from the charts and we have posted a couple of pictures we have taken to give a feeling of the quality of the charts. The charts we studied were clear and easy to understand (given access to the Russian alphabet). It looks like we will need to purchase two Volumes (Toms) to complete the sections from the White Sea to St Petersburg plus various lake charts and charts of the White Sea. Obviously there will be more charts needed to cover our exit from Russia into the Baltic. It could be quite an expense.
