Racing indoors certainly has its attractions at this time of the year and the Watt Bike Leagues in Norwich are now in their fifth week.

In the early evening session Helen Oliver leads the women while cycling photographer Mark Cozens tops the men's league.

However Cozens' new VC Norwich clubmate Simon Asher won three out of the five races in the fifth round - despite having cycled from Lowestoft to Norwich beforehand - so Cozens will have a tough task hanging on to his position on the final night.

In the later evening session Robert Hernstrom leads the series, just over a minute clear of Jason Turner.

See the Active Norfolk website www.activenorfolk.org/wattbike for details of two new Watt Bike leagues, on Tuesday and Wednesday nights.

Racing will start in the second week in March, but before that there are some taster sessions on Tuesday, March 2, and Wednesday, March 3.

Huge weather contrasts were encountered by cyclists at the weekend. A total of 26 riders started the VC Norwich Reliability Trial in wintery but not extreme conditions.

They passed Aylsham in good heart, but then, as the pace hotted up, the temperature plummeted.

Approaching Briston the splintering groups faced white-out conditions and it became difficult to see where the road was. Riders walked, or in some cases were helped to bigger gritted roads.

Organiser Malcolm Brown did a good job with a van and everyone was safely brought back to Norwich.

Another victim of the weather was the BMX Winter Series races at Sloughbottom, which were cancelled

However, at the opposite end of the region, Tricycle Association East members opted to lunch outside in during their meet near Danbury.

This Sunday's reliability trial is the Richard Clarke Memorial ride.

There is a choice of distances, 50 or 100 kilometres, starting 10 am from World Horse Welfare, Snetterton NR16 2LP and the organiser is Ken Jolliffe (telephone 01953 681755)

Mountain biker racers can start planning their year with several dates for the next twelve months.

Mud, Sweat and Gears are co-ordinating a summer league with races on May 2 in Tunstall Forest, June 13 in Thetford Forest, July 18 at Danbury Outdoors, August 15 at Codham Park, September 19 at Langdon Hills and October 10 at Chelmsford.

Thetford MTB's Dusk-til-Dawn is on the night of October 3/4, while the Whyte Winter Enduro dates will be November 7 and December 5, and January 30, and February 27, 2011.
